This example shows the number of patients per day as a bar chart, with days on the x-axis and patient counts on the y-axis. It loads a CSV file using the `csv` function from d3.v5 inside a React hook, then passes the parsed data to Victory Charts’ `VictoryBar` and `VictoryChart` components. The chart uses React’s `useState` and `useEffect` to fetch data asynchronously, and renders a fixed-width, 960×500 visualization with domain padding and custom tick label styles.
