Suggestion for a new spark-type : Min-Max-Average

[sag]

I my current project I am to show several items in a list and for each
item I will show several values (items vertically, different values
horizontaly).

But for each weekday the values vary, but I want to be able to show a
view that both shows the average value thoughtout the week as well as
the min/max within the week (how much variation we have).

To make it easier to read/compare value-type X for different items, I
want to use a spark-image.

The image would take as input:
- average
- min
- max

An example of what it would look like is shown here:

Does this sound like something that could be nice to include in
representqueens sparks?
