This example demonstrates a C3.js chart rendered alongside a second chart generated through a React component. The first chart displays two static data series, while the second chart, created via the `GerarChart` function, shows a different set of values. The code integrates C3.js with React 17, using the `c3.generate` API to create both visualizations. A file input and button are present, though their functionality is not fully wired to the charts.
