Which chart should I use for my data?
Paste a CSV: the tool reads the columns, applies fixed rules and tells you which chart fits, and above all why. The result is always the same for the same data, with no artificial intelligence.
Paste a CSV, choose a file or try an example to get a recommendation.

Paste the data
Paste a CSV or choose a file. Delimiter and header are detected on their own, and you can correct them by hand.
Check the columns
For each column the tool says whether it is a number, a date or a category. If it got one wrong, the recommendation will be wrong: look at the table.
Read the why
The recommended chart comes with its reasons, warnings and alternatives. Copy the Vega-Lite spec to draw it.
Suggerimenti
- If the recommendation surprises you, read the reasons: it almost always depends on the type I read for a column, not on the chart.
- A year written as a number must be named “year” or “anno” in the header, otherwise it is treated as an ordinary number.

How do I choose between a histogram and a bar chart?
A histogram splits a continuous quantity (heights, prices, response times) into intervals and shows how it is distributed. A bar chart compares distinct categories, or counts how many rows each one has. If the values are integers with few distinct values, they are treated as categories.
When do I need a box plot instead of bars of means?
When each category has enough rows. A bar showing the mean hides the spread: two groups with the same mean can be very different. The box plot shows median, quartiles and outliers.
Why does the tool almost never suggest a pie chart?
Because the eye compares angles and areas poorly, especially with similar slices. The pie chart remains among the alternatives when there are at most five parts and the share of the total matters.
Is my data sent to a server?
No. The CSV is read and analysed in the browser, and is neither stored nor sent. The recommendation is also computed here, from fixed rules.
