This fork of a reusable D3 scatter plot visualizes monthly sales data across product categories. The chart uses D3’s `scaleOrdinal` and `scaleLinear` to map months and sales values to SVG circle positions, with a color scale distinguishing six categories. An axis and legend are rendered via `axisBottom`, `axisLeft`, and appended SVG elements. The code samples data from a static array, demonstrating a reusable `scatterPlot` function with configurable accessors and margins.
