If you can get GeoJSON out of your postgis database, then you can use one of the new choroplethmapbox
chart types available in Dash 1.1.1
densitymapbox
chart type: https://plot.ly/python/mapbox-density-heatmaps/
choroplethmapbox
- GeoJSON choropleths: https://plot.ly/python/mapbox-county-choropleth/
(Many thanks to the organization that sponsored this feature (more about how to sponsor & fund our open source work: https://plot.ly/products/consulting-and-oem))
Thanks!
I´m trying to run the GeoJSON choropleths sample. I got the error message: ValueError: Invalid property specified for object of type plotly.graph_objs.Choropleth: ‘geojson’.
The dash version I have is 0.43.0 and I’m using Anaconda, and conda install shows that as the last version.
Should I update to Dash 1.1.1? How can I do that?

Now I updated to dash 1.1.1, from github, and after that I get the following error message:
File “mapFromPostgres.py”, line 37, in
fig = go.Figure(go.Choroplethmapbox(geojson=counties, locations=unemp.fips, z=unemp.unemp,
AttributeError: module ‘plotly.graph_objects’ has no attribute ‘Choroplethmapbox’
You likely need to upgrade the plotly
library as well
Ok, tks.
Shoudl I pick up from GitHub? How can I do that in Anaconda? There´s no setup.py there.
Tks!
I updated it from github (https://github.com/plotly/plotly.py) to version 4.0.0 and I get the error:
AttributeError: module ‘plotly.graph_objects’ has no attribute ‘Choroplethmapbox’
You need to upgrade to 4.1.0
, which is the latest version - Changelog here: https://github.com/plotly/plotly.py/blob/master/CHANGELOG.md#410---2019-08-06
Tks, it´s working nicely, now!
