FAQ
What data format does this expect?
One "label,value" pair per line — a label (text) followed by a comma and a number, like "Jan,12". This is the simplest common shape for quick chart data.
Can values be negative?
Yes — the chart scales its axis to fit the full range of your data, including negative values, and draws the zero line accordingly.
What is the difference between line and bar?
Line connects points in order — good for trends over time. Bar draws a separate column per point — good for comparing discrete categories.
Is my data uploaded anywhere?
No — the chart is drawn entirely in your browser using SVG. Nothing is sent to a server.
