Chart.js is quite customizable, and you can change fonts and styling in the Chart.js configuration object. Chart.js creates your charts on an HTML5 Canvas. To change background colour, one option is actually just to change the colour of the canvas which the chart is drawn on. We have seen you can add a Chart.js plugin to do this. In reality, this can just be an extra few lines in the Chart.js configuration object. Here just get the canvas context using `const ctx = chart.canvas.getContext('2d')`, then be sure to set `ctx.fillStyle = 'some-colour';`. In fact, you can even tweak this to set an image as the background, instead of a solid colour.
