This scatter plot visualizes the relationship between units sold and sales revenue for mobile devices, with data points colored by brand. The implementation uses a reusable `scatterPlot` module built with D3 v6, employing `scaleLinear` and `scaleOrdinal` for axes and color encoding, alongside `axisLeft` and `axisBottom` for chart annotations. The visualization cycles between two halves of the dataset every five seconds, fetched from a CSV via `d3.csv`, and renders as an interactive SVG with a 12-pixel font for labels.
