This looks really nice. Having a pause / resume feature and perhaps a manual horizontal scroll would make it even more awesome.

The vue.js is included twice. This seems wrong?

Also the data of the first contender is NaN instead of the actual values.

Changing the first line to Date,a,b,q,w,e,r,t,z,u,i fixes this problem but introduces another one. But that's for another ticket.

There should be a note on the webpage as to what is going to happen to my data that I upload.
Is it safe to upload sensitive data?

Labels are clipped when the values are small. Is it possible to have an option to either a) NOT clip the labels within the rectangle, or b) to display the labels to the left of the vertical axis?

Need horizontal scroll and fix mesuring axis values
