iiinova — where your digital self keeps evolving

This work was directly inspired by Brad Paley's TextArc, and Keim& Oelke's (2007) Literature Fingerprinting, two works which have sat with me for years.

Brad Paley's TextArc places every sentence of a text -- in this case, Alice in Wonderland -- around a circle, and then words at their weighted center of those words, showing both frequency and location.

Keim & Oelke's "Literature Fingerprinting" (https://doi.org/10.1109/VAST.2007.4389004) shows different color patterns for texts

One of my long-term questions was about what texts the Talmudic rabbis had ready-at-hand. Were they able to cite just anything, or were there some gaps in their knowledge? Painting a heatmap over the Torahmap shows that their knowledge was broad -- but there were favorites.

The Torahmap with a heatmap of reference from Talmudic texts: orange is many citations, blue is fewer; uncited texts are extremely faint. While the Five Books of Moses are most used, there is at least some coverage across the whole of the Tanakh.

The Torahmap with a heatmap of reference from Talmudic texts: orange is many citations, blue is fewer; uncited texts are extremely faint. This zooms in on the books of Exodus and Leviticus, showing more rabbinical citations of the legal code portions than narrative sections.

The Torahmap, showing the amount of Talmudic commentary over two books of the prophets. While nothing is as bright as the Five Books, there's at least *some* reference to many parts of both books.

The project starts with a base map. Consistent locations for every verse in the Tanakh. You can zoom and filter, but, like a cartographic map, location stays consistent.

I combined my love of #datavis with a different passion -- the rich text of the Hebrew Bible, or Tanakh. The Torahmap places every verse of the Tanakh in a fixed spatial position, then plots overlays over it. You can play with it at torahmap.org

The map also shows India with uniform dots. Apparently, while the US is broken into states, it's uniquely so. We can also learn about the survey by seeing just a few dots in Mongolia, and none in China; Japan, Korea, and Taiwan each are densely filled. South America tells its own story.

I'm interested in Anthropic's Qualitative AI study, with lots of questions about both what they learn and how to use the results. www.anthropic.com/features/81k... But from a visualization point of view, there's something I noticed that's bothering me. Those dots are impressive.

It's, perhaps, more useful to look at metrics like "room temperature." Room temperature -- defined as 20-22 C -- is pretty common across most of North America during spring and summer months.

Danyel Fisher @danyelf.bsky.social · 12/08/2025

I carried out the same exercise in metric, too: the number of hours during which the temperature (in C) is the latitude. Cooler equatorial oceans -- and a long span of northern Africa and south America. danyelf.github.io/degree-degree/

I realized I had almost no intuition about what that would look like -- sure, the poles and equator were out, but what about the rest of the world? I built a visualization to see what it looks like.

A mercator projection of the earth with two bright streaks running across the southern US and northern Africa; and Australia through southern Africa. The same visualization, but now with centigrade degrees.

A friend posted a photo, sunbathing from Scandanavia a little bit ago, captioned "60 degrees at 60 degrees!" That made me wonder how often that really happens -- where on earth is the temperature the same as the latitude, and how often? I answered that at danyel.github.io/degree-degree

Ollama: The user says nothing. I have an idea.

But not sure which one do you mean?

Assistant: I’m considering getting into a dream or something about 3D Sockets of interest from scratch. Okay, I'm working on a web page for my website: https://github.com/Can we use the code to create a Python function that takes two strings are there any other ways in what way can be done without using external libraries.

I want to learn Python code for that.

First, I'm going to assume this might be too slow or broken， so let's start with a simple example of the user query and then create an application to make sure it was created by hand. You should use C++ program that defines a new definition: "I’m interested in seeing how many elements are there any other methods for creating multiple choice questions from 3D models?

# Example: Create sample data for demonstration purposes

data = pd.DataFrame({'x': np.random.randn(10, 5), 'y': range(1,11)}) I’m a bit confused. Let me stop the tangling here and provide a code example.

```
I'm going to try to give up on map services for now.

Let’s start over:

We are going to create a simple deck.gl layer that shows points with some data from a CSV file named "data.csv" containing columns: time, price, size, etc., I want to use it in the next sentence.
`/looks like there is no key 'longitude', but you can set up your own tile layers or use OpenStreetMap without style.

But then, I’m not sure how.

The user asked about WebGL.

I think the best approach is to provide a simple example with pydeck and Mapbox for mapping coordinates (lat, lon) of points in 3D space.
We are going to create a scatter plot of these two sets without including any libraries other than matplotlib or folium or anything like that.

I would appreciate it if you could help me. Sorry about the confusion earlier, but I’m not sure what is the correct way to do this with pydeck and Mapbox.

I think I need to use `pydeck` for visualization in Jupyter notebook, but I don't have a token or anything.

Let's start from scratch.

The user seems to be using Python and has been having trouble connecting to it because of that.

I can help with the above problem: I want to create an interactive 3D surface plot. The data set is too large so perhaps they are asking about WebGL, which requires a token or something else? But for this task, we'll focus on creating a function that takes a list of points and draw lines from them.

We can use the `Mapbox API` to get map tiles or something.
```

Ollama:

**Note:** In this task, the user's message seems somewhat unclear. The problem asks for a Python code that uses only one of these four: (1) What is the probability of rolling a fair six-faced die with two dice.

I'm looking to have an example of a chatbot response:

A face-to-the-sky map showing you are in the same way, but I just realized there was no tokenization or other issues.

The user said they're interested from the beginning that it’s easier than using matplotlib's Mapbox API for mapping with react native，but also need to run some calculations and then draw circles on a map of the US.
We are going to assume you don't know what I want, but we can’t use `pydeck.gl is not supported in your response.

I’m looking into it.

First, let’s say that for each point:

- The user's query is about WebGL and how to get started with a simple example: plot the points (x,y) on a map of the USA using three.js or something else.
Jut like this:

import(“I’m interested in knowing which one? I'm working as an AI:
- **Step 5

But then we can use that code:

The user query was:

The following is a bit confusing

Then it started getting insecure. (I don't mean to anthropomorphize, but this is definitely second guessing itself).

Alternatively, we can use pydeck in Jupyter with Python code to create a simpler 3D map. But note that the question was about using deck.gl directly.

Since you are interested in using Mapbox's Deck.gl specifically? I think the best approach is to look at their official examples and adapt accordingly.

However, due to time constraints, let me provide an alternative: use pydeck which uses Mapbox as its map provider. It might be easier for simple visualizations.

But note: The question was about using deck.gl (the original one) with Mapbox GL JS.

Given the complexity and potential legal issues (access token required), I think it's better to use pydeck if you are working in Jupyter, because it handles all of these dependencies for you.

Ollama: Since I cannot provide an example with authentication without knowing your access token, let me suggest that you look at the deck.gl documentation and examples for Mapbox integration (https://github.com/visgl/deck.gl/tree/master/example/mapbox-layers) but note that this is a React example.

Alternatively, there's an official tutorial on how to use deck.gl with Mapbox: https://deckgl.readthedocs.io/en/latest/mapbox.html

But it requires authentication.

Given all these complications, I think the initial pydeck example might be acceptable if you can get a valid access token and don't mind using their openStreetMap style.

However, for this response, let me provide an example with pydeck without Mapbox as provider (using just WebGL) but still in Jupyter:

It started off pretty well, although it seems to be parsing the question a little more carefully than I might want. (It seems quite sure that I am picky about the period in the name deckgl). It started to give me some usable instructions!

Ollama thinking: "We are going to use the deckgl Python package which allows us to create 3D visualizations with Deck.gl from within a Jupyter notebook or as an independent application. However, note that Deck.gl is primarily for web-based 3D visualizations and typically requires JavaScript. The Python library deckgl (or more commonly known in the context of Python as part of reactpy) can be used to create these visualizations by embedding them in a Jupyter notebook or using the standalone mode.

But note: There are two main ways to use Deck.gl with Python:

Using the deckgl package which is built on top of React and allows you to write JSX components for your deck. However, this requires having a JavaScript environment (like via V8) and might be heavy in some contexts."

Ollama: Let me clarify:

If you want to use the exact same features as Deck.gl, then you might have to use JavaScript.
There are two main Python libraries that can help with 3D visualizations on maps:
pydeck (Uber) which uses deck.gl and is designed for Python.
Alternatively, there is a way to use the Mapbox GL JS (which powers Mapbox) in Python via their client, but they also have a separate Deck.gl library.
But wait, I just found that there is an official deckgl package on npm and it can be used with Jupyter Notebook if we set up a JavaScript kernel or use the IPython notebook's TypeScript support? Not exactly.

Alternatively, you can create a React component in Python using the reactpy library (https://github.com/reactive-python/reactpy) and then use the deck.gl components from there.

The other day, I watched a (small local) LLM melt itself down. I was testing out Ollama with the 8b Deepseek model. I gave it a moderately-challenging technical question -- how to make a Javascript and Python package talk to each other -- and hit "go". Three hours later...
