This choropleth map visualizes the user’s restaurant ratings across countries, with each nation shaded according to its review score on a red ordinal scale. Users click legend circles to filter countries by rating, which also dims non-matching regions and the background sphere. Built with D3 v5, the visualization uses `geoNaturalEarth1` projection, `geoPath`, and `zoom` for map interaction, while data is loaded via `tsv`, `json`, and `csv` from the World Atlas TopoJSON and a traveler dataset. Hovering reveals country names, restaurant details, and star ratings in tooltips.
