This scatter plot visualizes the relationship between horsepower and miles per gallon across cars in the Auto MPG dataset, with each point colored by cylinder count. The code loads data from a CSV file using `d3.csv`, applies `d3.scaleLinear` for both axes, and uses `d3.scaleOrdinal` with `schemeCategory10` for color encoding. Axes are rendered via `d3.axisBottom` and `d3.axisLeft`, while circles are appended with dynamic `cx`, `cy`, and `fill` attributes, rendered in SVG. The visualization includes labeled axes and filters out rows with missing horsepower values.
