This visualization analyzes Thai election data from a CSV file, presenting a bar chart of reported irregularities across electoral districts alongside a choropleth map. The bars are color-coded by severity level, with interactive sorting and tooltips. The map uses `d3.geoPath` to render GeoJSON boundaries and a bivariate color matrix to show the relationship between winning margins and reported problems. Both views are implemented with D3 v7, using `d3.csv` for data loading and `d3.scaleLinear`/`d3.scaleBand` for chart scales.
