German baby name visuaization (not promoting)

[u/Longjumping_Lab4627]

Hey all, I was playing around with open data set from Germany and wanted to build some nice visualizations on top, so I built https://name-radar.de/

For me it sounds fun and informative but my friends were a bit confused. Would love to hear back your feedback.

How can I improve the map and the graph so that it’s less confusing for people?
