Examples don't work as shown, due to Jupyter "Blocking request with no referer"

[maciejb]

I tried running the examples as shown in the docs, e.g. the CircleViz in the README, and the result is a blank map (tiles but no markers).

Looking at the Jupyter logs:

[I 17:19:42.806 NotebookApp] 302 GET /notebooks/points.geojson (::1) 1.54ms
[W 17:19:42.821 NotebookApp] Blocking request with no referer
[W 17:19:42.822 NotebookApp] 403 GET /files/points.geojson (::1): Blocking request from unknown origin
[W 17:19:42.824 NotebookApp] 403 GET /files/points.geojson (::1) 2.88ms referer=None

This can easily be worked around by storing the df_to_geojson() to a variable instead of a file, and reading that variable when creating the viz.

Tried with a few different browsers and both a local and remote notebook server. Is this an issue that can be resolved in the mapboxgl module, or should the documentation be changed?

We should update the documentation to use an in-memory variable assignment as opposed to a flat file export. The web servers that run various Jupyter environments have various configurations (cors settings, relative file paths, etc) that can cause issues with referencing a locally exported file.

Thanks for flagging this @maciejb

Encountering this too, I was only able to get it to work with c.NotebookApp.disable_check_xsrf = True, which is not recommended for security reasons.

Launching notebook jupyter notebook --NotebookApp.disable_check_xsrf=True also worked for me.

Closed with PR #170 - will roll into a new release in the next week.
