kaistha23/graph_d ? reverse-engineered prompt

Build me a self contained dashboard for connected counterparty analysis over a synthetic Saudi bank portfolio.

I want to be able to generate the demo from Python, then open one HTML file straight from disk with no server, no database, and no extra build tools. It should show the ownership and control relationships, group related entities together, apply the SAMA style limit overlay, and include a few network risk views like concentration and influence scores. Please make it easy to click around between the scenarios in the left side and focus on any entity.

The demo should include the four example situations from the README, especially the hidden conglomerate case, the shared board and address case, the supplier shock cascade, and the circular ownership loop. If you need to check anything, look up current docs online. Also make the output reproducible from a seed, and have it fail clearly if the input data is bad.
