08/26/2021, 10:53 AMCould you check if what Plotly has is sufficient? It would take like a day or two to add wrappers

08/26/2021, 1:44 PM@elect Lets-Plot has map component working in JVM and notebook alike. We can relatively fast add maps to Lets-Plot Kotlin API (at the moment maps only available in Python API). We have Geotools integration as well: https://github.com/JetBrains/lets-plot-kotlin/blob/master/docs/geotools.md
How urgently do you need maps in Kotlin?

08/26/2021, 4:45 PMDo you need to have it in JS or on a desktop? Plotly has this ability, so I can add this tomorrow (I think it will be nice to have it in lets-plot as well).

08/26/2021, 4:51 PMI see, no, animation of time series on map (in Lets-Plot Kotlin) can't be done in a week unfortunately.

08/26/2021, 4:51 PMon a desktop (I guess, I'll ask)

08/26/2021, 4:53 PMWe have dynamic plots in Plotly.kt, but on the desktop it requires web browser, so it will increase the size of the application like 30 MB, also you need to tell me what UI framework do you use. If it is OK to open it in browser, then no problems here and I can do it tomorrow in the morning.

elect
08/26/2021, 4:54 PMI guess the web browser is no problem at all, same as 30 MB overhead

08/26/2021, 4:54 PMI don't have preferences for the UI

08/26/2021, 4:55 PMAh, OK, then I will add this functionality tomorrow morning and add an example to the repository.

08/26/2021, 4:56 PMthinking about it, web browser is definitely a yes

08/26/2021, 4:58 PMOK, please ping me tomorrow at the evening if I don't write anything before that. Quite a lot on my plate right now, so I can miss something.

08/27/2021, 7:11 AM@elect I've reproduced some examples from plotly showcase. But I've found out that there are a lot of different map providers with different features. I do not think it will be possible to implement them all in a short time. To you know which specific map provider do you want to use?
e
elect
08/27/2021, 7:11 AMSaxony, but I don't know which provider
At this point, I'd say whatever provider is the simplest to have the Saxony map detailed enough

08/27/2021, 7:12 AMOK. I believe that you needs separate districts as tiles?

08/27/2021, 7:14 AMIf you have a https://geojson.org/ specified map, then it will be quite easy

08/27/2021, 1:30 PMI've moved the discussion to more relevant #science channel (do we need a separate channel for visualization tools?). But I've added the basic geo API to plotly.kt and released it in
0.5.1-dev-1repo.kotlin.link👍 2
