plot_emissions draws a plot of annual greenhouse gas emissions for the countries provided to the regions argument.

1	plot_emissions(df, regions = NULL, title = NULL)

`df`	A dataframe containing annual carbon dioxide, methane and nitrous oxide emissions records by country or region. It must include variables `iso_code`, `year`, `co2`, `methane` and `nitrous_oxide`, where `iso_code` is a code uniquely identifying each region. The greenhouse gases emissions units should be in million tonnes of carbon dioxide-equivalents. One such dataframe can obtained from Our World in Data: https://github.com/owid/co2-data.
`regions`	A character vector containing the codes of countries and/or regions that should be included in the plot. The codes must match those of the `df` variable `iso_code`.
`title`	The title of the plot. It is NULL by default.

The x-axis range of the plot goes from the earliest to the latest year with available data for any of the regions provided to the regions argument.

If the number of regions requested is between two and ten, a legend is added to the plot.

If not provided or set to NULL, all of the regions in df are included in the plot.
