A chart where each observation is a dot stacked above its value on a number line. Stack height is frequency: counting made visible.
Free AI dot plot maker
Paste a list of raw values (quiz scores, wait times, survey answers) and every observation stacks itself as a dot above its spot on the number line. Counting, sorting, and spacing handled; you just read the shape.

Dot plot or line plot? Same chart
In US classrooms it's a line plot; statisticians say dot plot. Either way: dots or Xs stacked above a number line, one mark per observation, stack height showing frequency. It's the most honest small-data chart there is: nothing binned, nothing averaged, every value visible. (Not to be confused with a line graph, which connects points over time.)
How to make a dot plot with AI in 3 steps
1Add values, ask for the plot
Paste the raw list, upload a CSV or Excel file, or connect a sheet. No tallying first, since repeats become stacks on their own. Then "dot plot of test scores" is the whole prompt. Working from a worksheet convention? Ask for X marks instead of dots.

Dot plot of test scores, mark the median28 scores, clustered high: the median is 9 and the tallest stack sits there too, with 8 of 28 students. The distribution is left-skewed, with a short tail down to 5 and nothing above 10.

One dot plot generator, four ways to stack it
Classic dot plot (line plot)
Frequencies above a number line. The chart every stats course starts with, because nothing hides.
Cleveland dot plot
Categories down one axis, a dot at each value along the other: a bar chart with the ink removed. Analysts' favorite for long ranked lists.
Dumbbell dot plot
Two dots per category joined by a line: before and after, this year and last. The gap is the story.
Grouped dot plot
Two datasets stacked in contrasting colors on one scale: class A against class B, control against treatment.
Why teams pick Deepnote as their AI dot plot maker
Understands the data
Raw values in, stacked dots out, with no pre-counting frequencies, and a marked median or a switch to X marks is one sentence away.
Stays connected
The dots follow the source (CSV, Excel, Google Sheets, or a database) so this week's plot shows this week's numbers.
Built for sharing
Publish an interactive plot, embed it in a doc or class site, or export a crisp still for slides and worksheets.
