Question

I m looking for some kotlin alternative to plot on a map like <http python visualization github io folium |folium> with python

altavir · Answer

I believe that there is a number of Java libraries Also it is possible to wrap leaflet itself Also if <https plotly com javascript maps |plotly maps> are sufficient for you we can add this functionality to Plotly kt on request

elect · Answer

I d need something asap unfortunately

altavir · Answer

Could you check if what Plotly has is sufficient It would take like a day or two to add wrappers

altavir · Answer

Do 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

Igor Alshannikov · Answer

I see no animation of time series on map in Lets Plot Kotlin can t be done in a week unfortunately

elect · Answer

on a desktop I guess I ll ask

altavir · Answer

We 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 · Answer

I guess the web browser is no problem at all same as 30 MB overhead

elect · Answer

I don t have preferences for the UI

altavir · Answer

Ah OK then I will add this functionality tomorrow morning and add an example to the repository

elect · Answer

altavir · Answer

OK 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

elect · Answer

ok as you wish thanks

altavir · Answer

< 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

elect · Answer

Saxony 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

altavir · Answer

OK I believe that you needs separate districts as tiles

elect · Answer

yep

altavir · Answer

I will try to find the best example Do you have a data sample I can refer to

elect · Answer

asking

altavir · Answer

If you have a <https geojson org > specified map then it will be quite easy

altavir · Answer

I ve moved the discussion to more relevant < CEXV2QWNM|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 1` should be accessible from jupyter etc with `repo kotlin link` repository Here is the example code All dynamic capabilities should work < Igor Alshannikov> if you have some kind of feedback it would be greatly appreciated I am still looking forward for kind of common plots API in kotlin
