How does MainPreset.js link to viz.py?

[JarethRajan]

From a previous discussion I made regarding file interaction between viz.py and the database, with the help of ktmud, I realised how the database connects to viz.p. However, I became unsure as to how MainPreset.js (which collects all the chart plugins) connects to the viz.py file. (Version 0.38.0)

My understanding of the relationship so far is as such.

• MainPreset.js is called by SetupPlugins.ts, which is then called by multiple App.tsx files.
• App.tsx files however are the highest branch and essentially start the entire program, there is no direct link from here to Viz.py.
• Viz.py BaseViz is called by multiple files, including utils.py (which I think might be the file that links?)
• viz_types is not called by many except "slice.py", which also calls "BaseViz"

Any help would be appreciated.
