How to make Altair plots responsive
There is no way to do this. The dimensions of Altair/Vega-Lite charts are pre-determined by the chart specification and data, and cannot be made to scale with the size of the browser window.
Can one make Altair plots fit the screen size, rather than have a pixel-defined width and height? I've read things about autosize "fit", but I am unsure about where to specify these.
