All involve awk or sed. That cuts out a large portion of the potential userbase...

Perhaps common uses could be wrapped in options to the script? For instance, an option to graph numbers on separate lines, to graph all numbers in the input in order, to graph a specific column of information (like passing through cut first) or to graph commonly graphed sources?

I feel like they're examples of really awesome use cases, so it shouldn't matter if people can't use them. Not to mention, I feel like this tool is targeted for terminal junkies who likely already have awk/sed.

Basically. Are there very many people who would generate sparklines, using a sh program - somewhere that has sh but not awk or sed?
