Nice article! As someone who implemented both clustering and heatmaps in Mapbox / Maplibre GL JS, just wanted to add that clustering isn't just a visualization technique — it's also a performance feature that can support other visualization types. It might not matter for 30k points, but for e.g. 300k, you can implement dot density with stacked opacity via clustering — use a tiny clustering radius, and style the dots so that opacity is a function of point_count. This creates an approximation of an unclustered viz that performs much smoother. Same thing with heatmaps — you can define heatmap-weight as a function of clustered source's point_count, and it will look nearly identical (aside minor shifts) as the unclustered one, but perform much better.

Amazing achievement, congratulations! Can't seem to be able to read it though, it greets me with "Sorry, you have been blocked" CloudFlare page — is this a HN overloading the website, or did the host accidentally block IPs from Ukraine perhaps?

You can read more about why most web maps are like this and a quest to fix this in this article: https://www.mapbox.com/blog/adaptive-projections

> Perhaps you see this conflict from the perspective of a sports fan

I see this from the perspective of a Ukrainian living in Kyiv. Your ignorance is mind-boggling, and after the laughable mention of "NATO biolabs" there's truly no sense in further conversation. These tinfoil-head "I do my own research" people are something else.

Russian war industry just burns reserves for nothing — hundreds of billions spent on missiles and long range drones didn't achieve any strategic objectives, all those expensive modern tanks, armored vehicles and artillery systems gets demolished by $500 drones, russian soldiers mass switching from military vehicles to donkeys, horses, bikes & buggies. Russia is no longer able to defend their vast territory against Ukrainian long range attacks so their oil refineries and military factories explode every day. 150k+ verified deaths (with names) already vastly exceed any russian wars since WW2 and we know there are many times more unverified ones.

Sevastopol nuclear base is irrelevant to modern warfare, and the fleet (both ships and subs) is either on the bottom of the sea (like the flagship Moskva) or gone to hiding in Novorossiysk because they can't defend against cheap Ukrainian naval drones.

Capture of cities not on the agenda — of course every time they fail spectacularly at something they'll claim they didn't plan it anyway, lol. They attempted and failed the capture of Kyiv, Kharkiv, Chernihiv, Sumy & Mykolaiv, then had to flee from Kherson & much of the Kharkiv oblast, and they are no longer strategically able to attempt capturing any more — only slow creep over obliterated rubble of small towns by sacrificing a thousand people a day in meat grinders.

I can't believe you can be so delusional, it's just amazing what russian propaganda does to people.

Soviet stockpiles nearly depleted, 1.5 million dead or wounded, Black Sea fleet practically destroyed, third of strategic bomber fleet destroyed, economy in downfall, no major cities captured in 4 years of all out war, gas and oil revenues plummeting, and there are STILL people saying “oh they just didn’t even start for real yet, just you wait”, gosh. Just laughable.

Not too fancy, but I built a math model & interactive visualization of my parking spot to understand how to efficiently park there without bumping into anything: https://observablehq.com/@mourner/kinematics-of-reverse-angl...
