This line chart shows automobile sales in India from 1999 to 2012, plotting yearly values as a blue path against time-based and linear scales. The visualization loads CSV data from a GitHub gist using d3.csv, then renders an SVG with d3.axisBottom and d3.axisLeft for labeled axes, while a d3.line generator creates the path. The React component uses d3.scaleTime and d3.scaleLinear to map data to pixel coordinates, with margins and tick formatting handled through d3-selection.
