Vertical resizing of visualization

[KevinDCarlson]

Currently visualizations just grow horizontally as far as they want. This is pretty bad for big instances and models like those active here: https://next.catcolab.org/analysis/0194487e-de41-72d0-bb79-ec47c1c0bbc7

If there's a GraphViz parameter that lets us insist on a given bounding box so that this wouldn't be too hard, it would be really nice to be able to drag the visualization box vertically taller and reflow the graph.

AFAIK, Graphviz does not let you set constraints like a bounding box, so that is not an option. (Someone should write a graph visualization tool with a flexible constraint engine but that's another story.)

What we can do:

• Provide a drag handle to resize the visualization in the vertical direction, like Notion does for various components; this would not change the layout, only the view of it
• Expose a few options for graph layout (directed or undirected, primary axis in directed case) to help work around bad layouts: this is partially implemented already but not exposed in the UI

Thanks. So for instance switching the primary axis on the instance I linked would make the visualization run vertically instead of horizontally, one hopes?

Yes, exactly.
