This reusable scatter plot visualizes the relationship between charging stations and EV sales across multiple years, with each dot colored by year using the Tableau10 color scheme. The code loads CSV data via `d3.csv` and renders an SVG chart with `d3.scaleLinear` for both axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and `d3.scaleOrdinal` for categorical coloring. The reusable `renderScatterPlot` function accepts configurable accessors and labels, demonstrating a flexible pattern for embedding charts in different contexts.
