This example shows a scatter plot of car data, plotting miles per gallon against acceleration, with each vehicle represented as a semi-transparent green circle. The visualization is built with D3 v5 and rendered as SVG, using `scaleLinear` for both axes, `extent` to compute the domains, and `axisLeft`/`axisBottom` for the labeled axes. Data is loaded from a CSV file via `csv`, and gridlines are drawn using negative tick sizes on the axes. The plot includes custom margin-based layout and styled text for axis labels and the title.
