Week over week comparisons/change over time

[djtran]

On one chart display average time per day for each difficulty as line trends for visualizing progress. Hopefully it's trending down and we're recognizing patterns!

[djtran]

Clarified the title to apply more broadly - create scripts for comparing the data compared to the last specified time period, whether it's day over day, week over week, etc.

frappe does not support incomplete time series data, choosing to plot all values adjacent to each other it seems. Either:

• explore alternate charting libraries
• fill the time series data with blank or empty data points

Since it's so early on in the project, I think looking into the former is more reasonable. Should think about use cases/requirements, and use those to compare/contrast.

A few other libraries like chart.js also require you to deal with imputing missing time data. The leetcoder inside of me is considering doing just that since the Date object allows you to simply add a day, etc. like I did here: https://github.com/djtran/Yet-Another-LeetCode-Timer/blob/master/src/extension/history.js#L151

I will continue with frappe and just impute 0s on days where there are no submissions.
