Offline Choropleth world map plot

[davidharris]

This seems peculiarly difficult. If you do the following, it looks like a step in the right direction, in that it tries to read the geojson file locally, but then hits a Cross-Origin Request Blocked error (visible in browser tools) that I don’t know how to bypass:

• Download https://cdn.plot.ly/world_110m.json to subfolder assets
• Add this option to write_html:

fig.write_html("worldmap.html", config={"topojsonURL":"assets/"})

I’m drawing on this post, which gives an alternative of editing plotly.min.js and also gives an alternative solution if using Dash

Loading geo assets offline [Solved]

I am running a Dash server offline and maps do not load. I can confirm that any map Graph runs if I have an internet connection but it doesn’t render if there is no internet connection (assuming this hasn’t been cached). Specifically, Plotly is looking for assets like https://cdn.plot.ly/usa_110m.json to render with. Is there a method to render this locally and offline?
