This reusable scatter plot displays sales trends over time, rendering day and sales data from a CSV file as red circles on a steelblue line chart. Built with D3.js v6, the visualization uses `d3.csv` to load the dataset, `scaleLinear` for both axes, and `axisBottom`/`axisLeft` for tick marks. The line is generated with a `d3.line` path, while the scatterPlot function exposes setters for width, height, data, and radius, making the chart customizable. SVG output is styled with the Share Tech font.
