This example renders a bar chart of monthly population counts using React hooks and Victory Charts. It loads data from a CSV file via the `d3.csv` method inside a `useEffect` hook, then displays the result with `VictoryBar` and `VictoryChart`. The chart maps the "country" column to the x-axis and "population" to the y-axis, with custom styling applied through Victory’s style props. The visualization demonstrates asynchronous data fetching and declarative chart composition in a React component.
