Map Chart

[reza1615]

There is huge potential on the map chart. It can be based on some free online maps or GeoJSON files. Plotly has an interesting map plot.
i.e. https://plotly.com/python/scatter-plots-on-maps/

I added "Maps" chart type as an option, but the data you supplied on houses seems to only have data for the northwest corner of washington so it produces kind of a dull map. :(

Need some more global data or at least data from around the entire US

[reza1615]

In the map chart window please link to GeoJson URL to download. and based on the downloaded file path it can generate the map.

I updated Lat and Long in the CSV file to have whole USA cities also added deltatime dtype. please use this zip file.

Looks like there still might be an issue with your lat/long values. This shows that they extend all the way to the north pole!

Sorry the kids had me watching Polar Express today :)

I had only 52 airports in all states so for the rest I added some random change to the lat and long.
try to filter them and only get 100-200 cases

[reza1615]

I updated the file. Now I added USA cities and states. you can test your code by state column.
also, I included 320K cities in USA in another file.

@aschonfeld : Just as FYI. For Lat and Long I found this link http://download.geonames.org/export/dump/
It hosted all countries lat and long.

[reza1615]

For map chart would you please use mapbox. It has more details and different maps.
https://plotly.com/python/scattermapbox/

based on below link if you set layout.mapbox.style properly it doesn't need token like
https://plotly.com/python/mapbox-layers/

[aschonfeld]

I can add scattermapbox to the "Map Type" drop-down. Nice find. Not sure how performant it will be but I'll def include it.

Just a heads up, anything that requires loading from the internet might be a while because this tool was supposed to be something that didn't require outside network connections. That being said I think if I present the user with a clear enough exception when they don't have a connection to the outside world it should be fine.

For offline support we should have access to GEOJSON to upload customized map. now offline map only have world (without country, state borders) + USA

[aschonfeld]

@reza1615 I've added the following static files to the app so that offline map generation is now possible (with some major hacking to plotly's JS as well 😉 )

• Scope -> world, Location Type -> ISO-3, country names: world_110m.json
• Scope -> usa, Location Type -> USA-states: usa_110m.json 67ms
• Scope -> europe: europe_110m.json
• Scope -> asia -> asia_110m.json
• Scope -> africa -> africa_110m.json
• Scope -> north america -> north-america_110m.json
• Scope -> south america -> south-america_110m.json

I'll create a separate ticket for allowing users to load their own custom topojson files..

Asia and world json have bug see them in github. last night I reported to plotly.js

[aschonfeld]

added v1.8.3
