A choropleth map of Venezuelan states shows each state’s percentage of votes for the first candidate in an election, using a threshold color scale from a blue sequential scheme. The visualization loads geographic boundaries from a TopoJSON file and tabular vote data from a CSV, then draws the map as SVG paths with `d3.geoPath` and a Mercator projection. The code applies a `d3.scaleThreshold` to map vote percentages to colors, with the fill for each state set based on its `porcentaje_1` value.
