0% is also the chances of me remembering to keep this up to date throughout the day, but have a look at it sometime next week and it'll probably be somewhat correct possibly* *unlikely #senedd26

Martin Chorley @mjc.martinjc.com · 08/05/2026

and with a massive 0% of the results reported, it seems like it's still all to play for in #senedd26 martinjc.github.io/wales-senedd...

I also threw all the feedback into notebookLM and generated a 20 minute podcast overview of the feedback as a tool to help students avoid the errors made by previous classes

Martin Chorley @mjc.martinjc.com · 10/03/2026

this is a nice way to practice analysis and vis skills, get some formative feedback on what they're doing, *and* encourage the class to engage with the previous year's feedback before they submit their own final assignments

100

Martin Chorley @mjc.martinjc.com · 10/03/2026

today in datavis class - we're looking at feedback for the final assessment. I gave out *all* the feedback I'd given for the last few years, students analysed it, then came up with some 'dashboard' type visuals to show what they'd found out

Martin Chorley @mjc.martinjc.com · 04/03/2026

Yes, lots of consideration and reflection, and a lot of interesting ethics discussions beforehand and afterwards

Martin Chorley @mjc.martinjc.com · 04/03/2026

A5 We've had students set up personas on tiktok or instagram and examine how easy it is to manipulate the algorithm to serve particular content or topics without explicitly searching for them - interacting with posts they think will eventually lead to where they want to go #LTHEChat

Martin Chorley @mjc.martinjc.com · 04/03/2026

Yes, think it's important to look at the whole ecosystem, particularly given how tightly coupled some of these systems are now (e.g. grok + X)

000

Martin Chorley @mjc.martinjc.com · 04/03/2026

A2 Yes, for now ... but really I think HE is too late. This needs to be embedded in earlier parts of the education system - so I'd like to hope eventually it would be something that students join us already being fully aware of #LTHEChat

Martin Chorley @mjc.martinjc.com · 04/03/2026

A1 filter bubbles for our students dictating what they see and hear ... a concern for well over a decade but I'm not sure how widespread or large the impacts really are. Concerns that AI will make things worse perhaps? #LTHEChat

Martin Chorley @mjc.martinjc.com · 24/02/2026

Yes, with slightly more realistic* data it looks a lot less busy and perhaps more understandable (*polling, with random seat distributions geographically, so take your realism with a pinch of salt)

000

Martin Chorley @mjc.martinjc.com · 24/02/2026

perhaps part of the problem is that we have too many parties. we should restrict it to two to reduce the colour clashes

000

Martin Chorley @mjc.martinjc.com · 24/02/2026

hmmm ... it's better than the contiguous I think, but the background is definitely needed

200

Martin Chorley @mjc.martinjc.com · 24/02/2026

Yes, I think that's a potential benefit. But having struggled with the difference between South and mid Wales in population terms I will now be standing for election on a single issue platform of empowering the boundary commission to forcibly relocate the people rather than moving the boundaries

010

Martin Chorley @mjc.martinjc.com · 24/02/2026

To place my hexagons and create the 'Wales' background, I needed to generate a hexmap of the shape of Wales. There are probably a few ways I could have done this, but the easiest was to boil an ocean to get Gemini to code me up a web app that takes in geojson boundaries and spits out hexagons

Martin Chorley @mjc.martinjc.com · 24/02/2026

Wales gets slightly less awkward if we try to use non-contiguous hexes. Next up, start adding 'fake' election results to see how they look with realistic results #datavis #dataviz #hexes #election #senedd

Martin Chorley @mjc.martinjc.com · 18/02/2026

In future rather than adjusting constituency boundaries according to population, we should adjust the population according to the constituency boundaries, to make the maps nicer. I for one will welcome the relocation to mid Wales, even if it does make the commute a challenge

000

Martin Chorley @mjc.martinjc.com · 18/02/2026

Wales is a really awkward country to turn into hexagons, but I think this just about works. martinjc.github.io/senedd-2026-...

I found myself with a little spare time this week, so finally finished a side project - writing some simple python scripts to download data from Strava and creating an animated timelapse of my running data over the last 15 years. Is it useful? Not at all. Am I pleased? Yes I am.

and it just did it. built the thing. found some errors. debugged and rewrote the thing. refactored and tidied the code. wrote me some docs. and it works.

Martin Chorley @mjc.martinjc.com · 07/12/2025

and some very basic prompts ...

a prompt for an AI coding agent: "hex.html contains two maps showing results of an election, and parliament contains a parliament diagram showing the same results. i need to create a single page showing all three diagrams at the same time. it should be flex, column order on mobile and row on desktop"

a prompt for an AI coding agent: "let's improve the interaction. each hexagon in the first diagram contains six smaller triangles. each of these triangles corresponds to a smaller hexagon in the second diagram, and a single triangle in the third diagram. when we click on a traingle or hexagon we should highlight the region to which it belongs in the first and second diagrams, and the related triangles in the third diagram.

we should also update the information displayed so it lists the winner of that seat and the party, not just the name of the area"

do we as educators need to shift from "here's how you write code" to "here's how you review code"? how much coding knowledge do you need to be able to steer and prompt and review efficiently and effectively? Some? None? All of it?

100

Martin Chorley @mjc.martinjc.com · 07/12/2025

to see these agents read my very basic prompts, analyse my code, design solutions and then check that they work ... this is disruptive, unnerving, and a little upsetting.

I think what I'm heading to here is an interactive ... start with Wales as a traditional geographic map, show how we can change it to a hexmap, break a hexagon down into six seats, show the full wales hexmap, then move into the parliament representation.

000

Martin Chorley @mjc.martinjc.com · 20/11/2025

What if you've presented your proportional results in your hex map and you want to transition that to a traditional parliamentary arc to show the proportions within the senedd? Yeah, we can do that ...

now we're getting somewhere. it's always the islands that cause problems! not drawing lines between the different segments of borders while we're transforming between shapes is the solution. the menai straits in Bangor Conwy Môn still look a bit iffy during transform ... #map #wales #senedd

ugh. path transitions. not fun. need to do some more maths here to polish this up

Martin Chorley @mjc.martinjc.com · 31/10/2025

This has been giving me a worry since I found out about it. Not sure this helps.

000

Martin Chorley @mjc.martinjc.com · 31/10/2025

I think the best result might be presenting both together? I'm not convinced yet that this works for proportional representation. Luckily we've got until May next year to figure it out

110

Martin Chorley @mjc.martinjc.com · 31/10/2025

Multiple hexes per constituency is also ... interesting. It's not really Wales shaped, but I think it just about works. Again, I suspect reordering the hexes within the constituency will give us a better overall sense of the results.

Martin Chorley @mjc.martinjc.com · 31/10/2025

Subdivision is ... interesting. I think there's some improvements to be made aesthetically in terms of the hexagon design. I think there's also something to be done with clustering parties together along boundaries to get a better sense of the overall picture (pre-attentive like)

100

Martin Chorley @mjc.martinjc.com · 31/10/2025

Proportional representation means we get six Senedd members per constituency, so we either need six separate shapes for each constituency, or will have to sub-divide each constituency somehow (basically the same thing, but leading to different presentation)

Today I've been thinking about how to visualise the Senedd 2026 results under the new proportional representation system. New electoral regions, which means new maps, in particular new hexmaps
