    I have a React component that basically draw some svg circles. How can I create a transition/animation between the two renders? What I would like is to see the points move from one position to another.

    const dataset = this.props.dataset
    <App>
      {dataset.map((datum, i) => (
        <TheCircle
          key={i}
          datum={datum}
          xScale={xScale}
          yScale={yScale}
        />
      ))}
    </App>
    
    const TheCircle: React.FC<Props> = ({ datum, xScale, yScale }) => {
        const { x, y, country } = datum
    
        const cx = xScale(x)
        const cy = yScale(y)
    
        let dotRef = useRef(null).current
        useEffect(() => {
          TweenMax.to(dotRef, 5, {
            cx: cx,
            cy: cy,
            ease: 'bounce.out',
          })
        }, [])
    
        return (
          <g>
            <circle
              className=""
              fill="none"
              stroke="black"
              strokeWidth={1}
              cx={cx}
              cy={cy}
              r={10}
              ref={(element) => { dotRef = element }}
            />
          </g>
        )
      }

     

    What I'm doing wrong?
