This example visualizes the growth of electric vehicle charging points in Germany over time, using a combination of an area chart and a line overlay to emphasize the upward trend. The visualization loads CSV data from a remote gist, parses years and numeric values, and renders them via D3 v7’s `scaleTime`, `scaleLinear`, `area()`, and `line()` APIs. The SVG output includes axes, labels, and a light blue background styled with CSS. The chart highlights the progression of charging infrastructure, with the area fill and black line both encoding the same quantitative values across the temporal domain.
