if watching Wales turn into hexagons and back is your thing, you can do that all day, baby

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

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

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.

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)

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

Decompressing from a very busy week. 2 conferences, 3 flights, nowhere near enough sleep.

7k shakeout last night, rainy lsr 18k this morning. Delightful.

Oli Hawkins from the FT talking about AI in the newsroom bringing together the most technical editorial staff with the most story focused technical staff ... I wonder if there's a masters out there for people who can bridge that gap?

Looks like we're doing a conference 😀👍

State of this. Absolute state. Unbelievable. In this day and age. Would you countenance it. Etc. etc.

Right. Out of office is on, and I'll not be doing *anything* even remotely looking like work until 2025. Bring on the holiday
