Customizing Axes
This example demonstrates a bar chart visualizing shift patterns for multiple employees over consecutive dates, with customized axes for readability. The chart uses D3 v5 APIs including `d3.nest` to group data by date, `d3.scaleBand` for the y-axis, and `d3.scaleLinear` for the x-axis, with `d3.axisLeft` and `d3.axisBottom` generating ticks. Axis labels are styled via CSS, and the x-axis tick format converts large numbers using `d3.format`. Data comes from a CSV file listing names, dates, and shift types, rendered as SVG rectangles.
