Add some kind of landscape plot in the background

[digitaltrails]

Add a long term trend plot in the background. Not necessarily a time plot. Probably a overall memory consumption trend or slope.

Perhaps an artificial-horizon memory rising/sinking slope:

• height = % consumed
• level line = static consumption
• rising to right = increasing
• decreasing to right = decreasing
• would probably need smoothing

Perhaps a curving line - long term smoothed, near term not so smoothed.

Perhaps stacked lines with one for buff/cache.
