Shown is a network graph of all Wikipedia articles and the links between them, resulting in a colourful representation of the world's collective knowledge. Among the most interesting findings are so-called communities, groups of articles that are more closely linked to each other than the rest of the site, represented by the individual colours.

If you consider yourself an established data viz practitioner, please please please consider applying!

Especially #D3js people! There are always way more mentees looking for d3 support in this program than there are mentors who could help.

Yes, y're right. Thanks a lot for pointing it out!
I forgot to exclude outliers from the legend color scale. There are two values, 2000 and 3160 of the personnel losses from the first weeks of the war, and the same for the APV category. Fixed it and added a spreadsheet view to the daily data.

I often use #Svelte #Scroller in #dataviz projects, and only recently discovered that it supports custom queries as a prop, and can work with any kind of HTML tags in the foreground, not just sections as it is by default. It's time to say goodbye to ugly, non-semantic "Untitled Section"
