Included here is code, data and discussion to support our paper:  [_On the use of ‘glyphmaps’ for analysing the scale and temporal spread of Covid-19 reported cases_](https://doi.org/10.3390/ijgi10040213).


In this repo is **code** for :

* Collecting and processing Public Health England's [daily cases data](https://coronavirus.data.gov.uk/) cases and geography datasets in [`./code/download_data.R`](./code/download_data.R)
* Pre-computing over the cases data for charting in [`./code/data_staging.R`](./code/data_staging.R)
* Helper functions for generating _ridge_ and _line_ charts in [`./code/helper_functions.R`](./code/helper_functions.R)
* Example code for generating and parametrising full _glyphmaps_ in [`./code/examples.R`](./code/examples.R)
* Code for generating [our implementation](./docs/img/wp.png) of this [Washington Post graphic](https://www.washingtonpost.com/nation/2020/05/24/coronavirus-rural-america-outbreaks/?arc404=true), a glyphmap of Covid-19 case data by US county:  [`./code/washington_post.R`](./code/washington_post.R)
