This dashboard visualizes Washington State electric vehicle adoption, showing average electric range trends over time for battery and plug-in hybrid vehicles, and vehicle distribution by county. It uses D3.js v5 to render SVG charts from CSV data, employing `d3.csv` for parsing and `d3.scaleLinear` for axes. A multi-series line chart and a combined bar and line chart include interactive tooltips and custom color schemes, with data grouped and averaged per year and county.
