A choropleth-style stacked bar chart displays Colorado county voting results from a local CSV dataset, with each bar split into yes and no votes. Users can interactively zoom and pan across the chart using D3's zoom behavior, which updates the SVG visualization in real time. The chart uses d3.stack to create layered bars, d3.scaleBand for county positioning, and d3.scaleLinear for vote counts. Tooltips appear on hover, showing county names and vote tallies loaded from the external CSV file.
