Questionable map accuracy for cities

[sampov2]

The "bubble map" places cities incorrectly on the map. This makes it difficult to a) find the city you are looking for, b) get an accurate overview of the spread. See attached screenshot from today where I have marked the actual locations for Tampere and Jyväskylä as opposed to where the bubbles are placed.

I understand that the visualization is chosen so that data points do not overlap, but the current implementation doesn't really provide the user with much usable information: Spatial accuracy of the results are lost as the bubbles are placed incorrectly

Hey, thanks for reaching out!

We're aware of the issue, and we've made a first fix already in #218. The current, unreleased-as-yet version looks like this:

That said, part of the problem in your screenshot seems to also be a very small viewport around the map. Is that from a mobile device?

It's good that the fix is underway, but as you mentioned it's not perfect. Espoo and Vantaa are way off in that picture.

The map was from Chrome on Linux on a normal laptop. Here is a full screenshot

☝️ here's the difference on mobile (left: prod, right: dev).

You're right, some locations are still off in more densely populated areas.

We'll see what we can do.

Instead of bubbles, you could try using actual geometries of municipalities - at least as an optional visualisation. Not as exciting as bubbles, but accurate. You can find good quality data from this service:
