This example visualizes WiFi network activity from a CSV file, displaying daily metrics for Connected users, Visitors, and Passersby over time using Victory Charts in a React application. The code loads the time-series data with D3’s `csv` function and renders it as a bar chart via `VictoryBar` and `VictoryChart`. The visualization shows how daily interactions fluctuate, with a noticeable spike in usage around mid-July. The chart uses a custom style with large tick labels and fixed dimensions, demonstrating the integration of React hooks (`useState`, `useEffect`) for data loading and rendering.
