How (and why) to transpose a dataset

Transposing a dataset means swapping its rows and columns so that the rows become columns and the columns become rows

Let's say we have the following table:

Blueberries 1 Dollar tasty
Fennel 2 Dollar not tasty at all 

After transposing, it will become this table:

Blueberries Fennel
1 Dollar 2 Dollar
tasty not tasty at all

You can see that the names in column 1 became the first row in the transposed table. The dollar values in the second column moved into the second row, and the taste assessments in column 3 became the third row.

With a bit of experience using chart types, you will be able to prepare the data accordingly, even in Excel or Google Sheets.  

There are options to transpose data in both spreadsheet applications, although they tend to be a bit more complicated than to transpose the data in Datawrapper. These links offer more explanation if you want to try it:
