This example shows the relationship between the release year and price of LEGO sets, using a colored background rectangle to highlight the plot area. The code builds on a scatter plot template and uses D3’s `scaleLinear` and `extent` to map data values to pixel coordinates, while the `@curran/axis-labels` library positions the axis labels. The data comes from the `@Landaman/lego-csv` dataset, with each circle representing a set, and the chart’s dimensions and margins are configurable through the main module.
