This fork of a scatter plot displays data on cars from the UCI Machine Learning Repository’s Auto MPG dataset, plotting horsepower against weight as red, semi-transparent circles. The visualization uses D3 v5 with the `select`, `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` APIs to parse the CSV, compute scales, and render SVG axes and circles. A title labels the chart as an “HK Temperature Heatmap,” while grid lines and rotated axis labels structure the layout.
