Transform Contribution Matrix into Visualisation?

[nelsonic]

This is a sample contribution matrix graph for the past year for a random person:

I want to represent this data in a more visual way to emphasise the fluctuations in contributions.

This is the most basic line graph with a single color:

What I want is the area under the line to be shaded with the color of the "fill".

This one failed but it's still interesting from an artistic perspective:

Slightly closer to what I wanted (but not quite there...):

Red denotes days that have zero contributions:

Sadly, this visualisation does not improve upon the standard Contribution Matrix ...

Think I'm going to try the bar chart next: https://observablehq.com/@d3/bar-chart ... 💭
