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](https://cdn.plot.ly/world_110m.json) to subfolder _assets_
- Add this option to write\_html:

```python
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

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](https://cdn.plot.ly/usa_110m.json) to render with. Is there a method to render this locally and offline?
