TypeScript type cast D3 js errors

Question

Now, how should I solve this/typecast this?

import { useEffect, useState } from "react";
import { arc, pie, DSVRowArray, csv, PieArcDatum } from "d3";

const CSVURL =
  "https://gist.githubusercontent.com/mzs21/df0621d1ca5a25fa6baeeae93562c1a1/raw/CSSNamedColors.csv";

const width = 960;
const height = 500;
const centerX = width / 2;
const centerY = height / 2;

const FetchData = () => {
  const [data, setdata] = useState<DSVRowArray<string>>();

  const pieArc = arc().innerRadius(0).outerRadius(width);
  const colorPie = pie().value(1);

  useEffect(() => {
    csv(CSVURL).then(setdata); // Fetching data & updating data
  }, []);

  if (!data) {
    return <pre>loading...</pre>;
  }

  console.log(data[0]);

  return (
    <svg width={width} height={height}>
      <g transform={`translate(${centerX}, ${centerY})`}>
        {colorPie(data).map((d: PieArcDatum<number>) => (
          <path fill={d.data["RGB hex value"]} d={pieArc(d)} />
        ))}
      </g>
    </svg>
  );
};

export default FetchData;

The code executes but with error in VSCode. Errors of VSCode are in the picture.

I'm also pasting the errors here:

In CodeSandBox it's working fine. No error. Playground : https://codesandbox.io/s/frosty-cannon-bfxprg?file=/src/FetchData.tsx:0-975
