I made a Svelte component wrapper around Rough.js for creating graphics with a hand-drawn, sketchy appearance 😄

Agreed. This why I build a dedicated website for bike counters in Montreal: compteurs-cycliste.r42.ca So people can actually get an overview or a more complete picture on how much cycling has gained traction over the past years. Thanks for sharing @ohtheurbanity.bsky.social

compteurs-cycliste.r42.ca

Montreal Bike Counters

Interactive dashboard of cycling activity across Montreal, based on open data from the Ville de Montréal.

... not open source, and as a very specific website project, I would doubt getting any stars 😅

I haven't even tried LayerChart waffle or treemap, as I am using my own version, that is also published in the PowerBI Marketplace. These are very easy to use, when you know them and all the features are built-in. The Treemap is a polygon treemap, with automatic label density stuff.

@techniq.dev - my first public project using LayerChart 2. Was a real pleasure. Bar charts + Sankey were created with your library, Waffle and Treemap are based on my own #Svelte library. I would love if you could use this as a reference 😁

I am using #LayerChart from @techniq.dev for the first time and I am absolutely stunned how well IA agents can understand and translate my requirements (series labels with dodging, #dataWrapper style date axis, modern gridlines, line interpolation..) This task took me weeks when I hand coded them!

Preparing a new micro website with team stats of the #WorldCup2026. Preview - should be ready before we know who wins.

I added a new visual to the #Montreal #bikeCounter project. Which bike counter sees the most cyclists — and does that change over the year? Hover over the lines and find out. Data updates daily, the race is on. Project: compteurs-cycliste.r42.ca

Ralph Spandl @spandl.ca · 25/06/2026

All visualizations (except the map) in this project where built with #SveltePlot by @driven-by-data.net. Very nice to work with, offering quite some flexibility in terms of custom marks and responsive adaptation.

Public data is only useful if people can actually use it. After Montréal restored public access to its bike counter data last month, I decided to built a dashboard to explore cycling trends across these counters. 🚲 compteurs-cycliste.r42.ca Regularly updated as new data becomes available.

There are a lot of interesting chart variations in this addendum to the report of the Canadian Climate Institute. I guess, I should read the report to entirely understand them 😅

Ralph Spandl @spandl.ca · 17/06/2026

This is mentioned in the sign up form: Are you currently based in the U.S.? (This study requires participants to be located in the U.S. (compensation is paid by check).) Not quite clear, if this is only related to the compensation, but I assume there is another reason for it.

Ralph Spandl @spandl.ca · 17/06/2026

But you need to be located in the US, it seems.

This is not an analytics reporting (...Magritte, get out of this body). But about the post-modern data stack, or how to build the digital analytics solutions of tomorrow... ..a glimpse into what a future digital analytics data stack output might look like. #DataViz #Analytics 1/6🧵

Ralph Spandl @spandl.ca · 29/04/2026

Nice to see, that you are making progress on your project. I think analytics dashboard will take the web path: There are so many different ways how you want to see your data - adapted to the audience - that no BI tool can cover all these possibilities. So, back to DIY, using a web stack.

Another great example showing that flags are a misleading way to represent languages. Even ignoring the Reggaeton vs. Spanish point, most songs people listen to don’t come from England but from a wide range of places—just as “Europe vs. the rest of the world” oversimplifies reality.

New in SveltePlot: Raster Mark I don't understand yet the full concept, but it allows you too interpolate values to create a raster in image format. svelteplot.dev/marks/raster Kudos to @driven-by-data.net

When D3 was released in February 2011, it transformed how we build data visualizations for the web and ushered in a new age of unbridled creativity in information design, data journalism, and beyond. Today, it remains the backbone of modern, interactive data viz. Happy 15th birthday, D3 🎂 d3js.org

This new visual start to work out really nice: A Likert scale bar chart with neutral values in the center and automatic calculations of the overall score (in this example: net score). Still a few features missing, but getting there.

Development environment of new Power BI visual

Ralph Spandl @spandl.ca · 18/02/2026

The Winter Olympics are almost over. A good moment to look back at the stream of medals over time. The Olympics try to stay apolitical, but this steamgraph still reflects European history, much like cold winters leave marks in a tree’s rings. Created in #PowerBI with: r42.ca/articles/tim...

$Olympic Winter Games, 1932–2022 Higher, faster — and more medals. At first glance, the steamgraph reflects the steady expansion of the Games themselves: more disciplines, more events, more podiums. Look closer, though, and it also compresses decades of political history into a single shape. The green band traces the forty years of a divided Germany. The red band tells a more fractured story: across the decades, Russian athletes appear under four different names, each change driven by politics rather than sport. In absolute terms, medals attributed to countries outside the top 15 increase over time, whether their share truly grows is less clear..$

When running #DataViz workshops, one question that often gets asked is "what's your favourite ever chart?" 📊 So I've started compiling some of the awesome visualisations made by other people that I often share! A very much a work-in-progress, non-exhaustive list: nrennie.rbind.io/fave-data-viz/
