Running this on WSL2. Graphics works (for instance, Firefox comes up no problem).  
Trying to use PlotlyJS I get this error message:

Any idea what to do?

I have had an epiphany and read the documentation ;):

Trying to run `electron` I found that some libraries are missing in Ubuntu 20.4 when installed as WSL2.  
Doing

```julia
sudo apt install libnss3   
sudo apt-get install libxss1 

```

fixed the issue.
