This scatter plot visualizes walking steps taken each day in November, using red circles to map date against step count. The data comes from the UCI Machine Learning Repository's Auto MPG dataset. Built with D3 v5, the code uses `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to construct axes and scales. SVG circles are positioned via `attr('cx')` and `attr('cy')`, with axis labels and titles styled through CSS classes like `.axis-label` and `.title`.
