How to make a line graph with AI in 3 steps
1Add data, describe the graph
Drop in a CSV or Excel file, connect a Google Sheet, or paste values in — then type "plot weekly signups for the last quarter" and the AI draws it. Dates and numbers are picked up on their own.

One line chart maker, four types of line graphs
Simple line graph
A single line tracking one value over time — revenue by month, temperature by day. When the story is the trend, this is the chart.
Double line graph
Two lines, one comparison: this year against last, plan against actual. Add a second value column and both lines get drawn and labeled.
Multiple line graph
Several series on shared axes, each with its own color and legend entry. Best kept to a handful of lines — after that, consider small multiples.
Curved line graph
The same data with smoothed lines instead of straight segments. Easier on the eyes for presentations; keep straight lines when precision matters.
Why teams pick Deepnote as their AI line graph generator
Understands the data
Ask for a 7-day rolling average, a trend line, or a second y-axis — time-series requests a basic line graph maker has no button for.
Stays connected
Connect a CSV, Google Sheet, or live database and the line grows on its own as new weeks land.
Built for sharing
Publish an interactive graph, drop it into docs and sites, or export a still that matches the numbers in the meeting.
