If you're interested in how it works, the source code can be found here. It is a SvelteKit app using Maplibre for the map rendering. The custom dot density functions can be found in /src/lib/make-points.js

Experimental interactive dot density map. Contribute to ONSdigital/dot-map-poc development by creating an account on GitHub.
The points are placed using custom code based on Mitchell's best candidate algorithm to achieve an even spread. More points are generated as you zoom into the map, and the point locations and colours remain consistent as you change years.

#30DayMapChallenge Day 1: Points
Worked on this experimental dot density map using UK population data by age and sex. The points are generated and coloured in real-time as you explore the map.

#PlaceNameTweener was inspired by this exceedingly silly map by
@terriblemaps. All of the code is open source and can be found here on GitHub
https://github.com/bothness/placetweener Have you never wondered what made up places you might find between
#Iceland and
#Ireland, or between
#Northampton and
#Southampton? Today, you can open up this new world of possibilities with
#PlaceNameTweener, inspired by

https://bothness.github.io/placetweener/This new tool is released alongside the latest official UK population projection, which is for an increase of 4.9 million people (7.3%) between mid-2022 and mid-2032, from an estimated 67.6 million (2022) to 72.5 million (2032). You can read more here:

The potential future population size of the UK and its constituent countries. These statistics are widely used in planning, including fiscal projections, health, education and pensions.
📈📉We've just published a nifty new
#ONS tool that allows you to see how different factors affect population projections! Adjust life expectancy, fertility rate and net migration to see how they affect estimates...

An ONS interactive tool showing UK population projections based on changes to life expectancy, fertility and migration.
Added a zoom control to
#AnyMapPuzzle to give more control over the area of play. Here's an example for the Great Pyramid of Giza. You can zoom to cover pretty much the whole world if you like...
