Questions
Does it make a PNG?
No. This tool outputs an HTML file with an inline SVG chart. That is stated honestly here and in the README, because a pure-stdlib PNG chart writer is not reliable.
What CSV format does it need?
Two columns: a label and a number, with a header row, for example Month,Sales.
