This scatter plot compares automobile horsepower and acceleration, with each data point’s size encoding model year and its color shading from black to blue representing vehicle weight. The visualization is rendered as an SVG with animated transitions using D3 v5. The code employs `scaleLinear` for all four axes, `axisLeft` and `axisBottom` for grid lines, and `format` for tick labels. Data is loaded asynchronously from a CSV file via the `csv` function, with numerical fields parsed before the `render` function generates the animated circles.
