## The chart is the fastest way to see the shape

A table tells you what the numbers are. A chart tells you which one is unusual. Getting from a raw export to that picture is normally a detour through a spreadsheet, a pivot table and a formatting fight. Two dropdowns is enough, as long as the tool does the grouping for you.

### Repeated labels are grouped, not overplotted

Raw exports have one row per order, not one per country. Plotting them directly gives you forty bars where you wanted five. Rows sharing a label are combined first, and you choose whether that means summing them, averaging them or just counting how many there were.

### Pick the form for the question

Columns compare magnitudes across a handful of categories. Horizontal bars do the same when the labels are long. Lines and areas are for change along a sequence, usually time. A pie only answers what share of the whole, and only when there are a few slices, which is why the tail folds into one rather than splintering.

### Readable by more people than you think

The series colours are fixed in order and checked for separation under the common forms of colour blindness, a legend is shown whenever there is more than one series, and the underlying numbers are one click away as a table. Colour is never the only thing carrying the meaning.

## Questions

### Is my file uploaded?

### Why are my rows being combined?

### Can I plot two columns with very different scales?

### How many series can I add?

### What is the difference between the SVG and PNG export?
