Charted roots - graphic view configuration

What I’m trying to do

I want to build a genealogical graphic relational graph. I have imported my gedcom to charted roots. As a matter of fact, charted roots’ graphic view shows not only people, but places, birth, death and occupation. As there are more than 900 people n my tree, it gives an impossible layout to visit.

Things I have tried

I tried to fix the problem into the charted roots settings , but it appears that in the canvas settings places, birth, death, occupation are already unchecked. Google AI told to create a CSS file to hide unwanted data in the appearance menu of Obsidian. It changed nothing. I am not surprised : the problem belows to Charted Roots, not to Obsidian in itself.

Thank you for your helping.
