This scatter plot shows the relationship between driving range and price for electric vehicles in Germany, using color saturation to encode efficiency and revealing a general trend where longer-range vehicles tend to cost more in euros. Built with D3.js, the visualization uses `scaleLinear` for both axes, `axisBottom` and `axisLeft` for ticks, and `circle` elements with `colorScale` mapping efficiency from teal to purple. The data comes from a Kaggle dataset on electric vehicle specifications and prices, with missing "NA" values appearing as points outside the main plot margins.
