The interest over time graph uses spline interpolation to connect the datapoints, while that might look prettier than straight lines, it is something that is strongly discouraged in a scientific / data analysis context, because the curving line does not carry meaningful information.

Hey there,

I agree with your analysis, actually. I'll try with straight lines and see how it looks!

Thanks for the feedback!

There are other more valid ways to make a curved line.

If your data points are equally spaced in time, look into 'sinc interpolation'

Interesting, thanks!

Do you mind pointing to some links that explain why?
