Customizing Axes
This bar chart tracks new confirmed COVID-19 cases in Alameda County by date, using data from a local public health dataset. The visualization emphasizes the customizable nature of D3 axes, with rotated date labels, a formatted time axis, and horizontal gridlines extending from the y-axis. Built with D3 v5, it uses `scaleBand` for the x-axis, `scaleLinear` for the y-axis, and `axisBottom` and `axisLeft` with custom tick formatting via `timeFormat`. The SVG rendering includes an axis label, a rotated title, and blue bars sized by `xScale.bandwidth()`.
