# Duaer Our World in Data

Duaer Our World in Data reads the data behind an Our World in Data chart for chosen countries, newest year first. Without a chart, it finds charts that match your words.

## When to use

- Compare countries on a long-run indicator such as life expectancy.
- Find which chart covers a topic, then read its data.

## When not to use

- Official national accounts. Use https://skills.duaer.com/world-bank.md.
- SDG series by code. Use https://skills.duaer.com/un-sdg.md.

## Parameters

Provide `chart`, or `words` to find charts.

- `chart` — Chart slug from the chart URL, such as life-expectancy or co2-emissions-per-capita.
- `countries` — Optional. ISO codes such as CHN,USA; OWID_WRL is the world. Default CHN,USA.
- `words` — Optional. With no chart, list charts that match, such as electricity from solar.
