Cluster-map not showing

[pandrich]

I am trying to replicate the global power plants example to test the cluster map extension of datasette but no map is shown after I launch the application.

I created a separate virtual environment for this test in which I have only python 3.8 and datasette, its plugins and relative dependencies (see below). I installed the plugins using datasette install as suggested to make sure to install the packages appropriately within the environment.

When I pull up the database all seems to go well with fetching the plugin but the map is not shown.

I think it is likely something I am doing wrong but I cannot find a hint of where the problem might arise. Any thoughts?
I should also mention that the datasette-vega plugins works instead correctly.
Thanks for your help!

Those logs suggest that this should be working. The ?_shape=array&_shape=array thing is weird - I've started seeing that myself too.

Hey Simon, I should mention that I tried to run this on Linux (through WSL installed on my Windows machine) and all works perfectly ( I was worried that some settings might have been off with the visualization in my browsers). Something's up with running it purely on Windows but I can't figure out what. Not sure if this can help.

@pandrich I think this can be solved by updating a registry key in windows. This Stack Overflow answer fixed it on a Windows Machine for me

[pandrich]

@ryancheley I just tested this on Windows and it works perfectly! Thanks for the tip!

[ryancheley]

@simonw not sure if you’d want to have the README (or some other part) updated to include this tip. If so, I’d be more than happy to write something up and submit a PR!
