A dashboard visualizes election irregularities across Thai constituencies, mapping problems, invalid ballots, and voter turnout. It renders Thailand's electoral boundaries from a GeoJSON FeatureCollection using D3 v7's `d3.geoMercator` and `d3.geoPath` into an SVG, with D3 zoom for panning and scaling. Interactive tabs and hover tooltips show province names and constituency numbers. A summary card displays struck-through placeholder counts, while a bar-chart area remains empty, awaiting data binding.
