A clear answer. Here’s how.

Parses a local UTF-8 comma-separated CSV. Bar and line charts group identical non-empty labels in first-seen order and use the chosen sum, mean or count; at most 100 groups. Scatter plots use two finite decimal numeric columns, preserve row order and allow up to 2,000 points. Blank numeric cells are skipped and counted; malformed numbers are rejected. Up to 10,000 input rows. Charts use linear axes, include zero for bars and can be downloaded as self-contained SVG with a CSV of plotted values. Line charts connect first-seen categories, without inferring dates or sorting.

Keep going.
