This interactive bar chart compares the current and extended EV range for various vehicles, highlighting the impact of the GTC Range Extender. It uses D3.js v5 with an SVG rendering approach, leveraging `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to construct the visualization. The data is loaded via `d3.csv` from a GitHub gist, with green bars representing current range and orange bars showing the enhanced range, accompanied by a legend and value labels for clarity.
