This example demonstrates a reusable scatter plot visualization of laptop sales data, showing the relationship between cost and quantity sold. It uses a D3.js module pattern to create a configurable chart component, with the `scatterPlot` function accepting setters for dimensions, margins, and data accessors. The data is loaded from a remote CSV file via `d3.csv()`, then parsed and rendered using `scaleLinear` for axes and `axisLeft`/`axisBottom` for tick marks. The implementation includes TODO notes about making the chart idempotent, and the page uses custom styling with the Share Tech font.
