Statistics and graphs for 2-column csv files — a start. The example above is time series data. I plan to add other data/plot types later, e.g. scatter plots. Also, the ability to grab data directly from a URL.
The data used in the example above is in the file temperature-anomalies.csv in this repo. It is a list of global temperature anomalies for the period 1880-2017 from www.climate.gov. The annual temperature anomaly is the difference between the global mean temperature and the long-term average global temperature. For this data set, the long-term average is computed for the period 1901-2000. Here is what the data looks like:
