A stylized bar chart visualizes time-series data, mapping document counts to vertical bars. The chart displays data points over a date range, with the y-axis auto-scaled to the data's extent. Built with React and D3 v5, it uses `scaleTime` and `scaleLinear` for positioning, rendering SVG rectangles as bars. The data comes from a local JavaScript array simulating a time series, with axes created from custom React components rather than D3 axis generators.
