title: custom tooltips with react-chartjs-2 library
body: <p>I am having issue with the default tooltip that chartjs provides as I can not add html inside the tooltips. I had been looking at how i can add the html/jsx inside the tooltip. I see an example with using customized tooltips here <a href="https://stackoverflow.com/questions/39025737/chart-js-show-html-in-tooltip">Chart JS Show HTML in Tooltip</a>.
  can someone point me an example how to achieve the same with react-chartjs-2 library?</p>
