Currently our only writer module is for vegalite, the output is a vegalite spec (JSON). Tools already exist to render this kind of output to an interactive chart, SVG, PNG, etc. with their own controls for sizing and the like.

Our ggsql Jupyter kernel can use these vegalite specifications to output charts in a Quarto document, for example.

In the future we plan to create a new high performance writer module from scratch, avoiding this intermediate vegalite step, at which point we’ll have better answers for your questions!
