One row per figure, so you can filter it by chart in any spreadsheet. The columns:
- Chart and Chart URL: the question the figure answers, and its page.
- Label and Value: the year, state or thing, and its number, unrounded.
- Margin of error (±): for survey estimates that have one; blank otherwise.
- X label and Y label (unit): what the labels are, and the unit of the value.
- Data as of, Source and License, with their addresses.
Look-up charts, which hold more than one file can show, are left out; each has its own page. Developers can get the same charts as JSON from the data feed.
How to credit
Wherever you show or quote these numbers, credit the source as its license asks and name Chartly with a link to the chart (each row has its address). For example:
Data: U.S. Bureau of Transportation Statistics, Airline On-Time Performance (Reporting Carrier On-Time Performance, 1987–present), via Chartly (https://chart.ly/charts/flight-delays-by-time-of-day).
