This combined chart displays voting data over time, using a bar chart to show Democrat votes and overlaid line charts for Republican and Independent votes. The visualization is rendered as an SVG graphic using the D3.js library, with a clean white background and labeled axes. Data is loaded from a CSV file and parsed to numeric values, then scaled using D3's band and linear scales. A legend and gridlines help distinguish the data series, while the x-axis labels are rotated for readability.
