The react-chartjs-2 set 200 to width and height of the canvas by default.
A W3C document define them 300 and 150 as default value.
The width attribute defaults to 300, and the height attribute defaults to 150.
The Chart.js is not set width and height of the canvas by default.
As a result, the aspect ratio of the canvas is 2.
But the react-chartjs-2 is set 1 to the aspect ratio of the canvas.
I am confused by this.
