Illustrate the correct use of useState hook to update chart data dynamically, ensuring the chart re-renders properly when new data is received.

import React, { useState, useEffect } from 'react';

Importing necessary hooks from React.

import { Chart } from 'path-to-tanstack-react-charts';

Importing the Chart component from TanStack React Charts.

const DynamicChart = () => {

Defining a functional component for the dynamic chart.

  const [data, setData] = useState([]); // Initialize data state

Using useState to manage the chart data.

  useEffect(() => {

Using useEffect to fetch or listen for data updates.

    const fetchData = async () => {

Defining an async function to fetch new data.

      // Example API call to get new data

Placeholder for data fetching logic.

      const newData = await someAPI.getData();

Calling the API to get new data.

      setData(newData); // Update the state with new data

Updating the state with the fetched data.

};

Closing the fetchData function.

    fetchData();

Invoking the fetchData function to fetch data on component mount.

  }, []); // Empty dependency array means this runs once on component mount

Ensuring fetchData is called only when the component mounts.

  return <Chart data={data} />; // Render the chart with the state data

Rendering the Chart component with the state data.

};

Closing the DynamicChart component function.

export default DynamicChart;

Exporting the DynamicChart component for use in other parts of the application.
