Summary

Your Charts lacks of drawing the trendline of the values on the charts. But, this is a simple thing to do.
It is possible to calculate and it manually. But, it should be a parameter: trendline: true. Maybe some additional configurations, like color, transparency, line type...

Justification

It is quite obviously why it is needed. A trendline should be a built-in feature for charts.

Desired UX and success metrics

Ideally, it should be a object in the options.js like:

trendline: {
   enabled: {
      'key': true,
   },
   color: {
      'key': #hex,
   },
   transparency:{
      'key': 80,
   }
}

"Must have" functionality

At least "enabled" features with 'parent color'.
