This dashboard visualizes election irregularities in Thailand, showing the relationship between close electoral races and reported problems, invalid ballots, and voter turnout. It combines multiple D3.js v7 charts, including an interactive map of provinces with toggleable modes, a bar chart, a pie chart, and a scatter plot, all driven by a CSV file of district-level results. The code uses d3.csv for data loading, d3.rollup for aggregation, and d3.pie/d3.arc for the donut chart, with custom tooltips and color-coded party legend for user interaction.
