Sunburst plot of PubChemLite (14 January 2020 tier1 version [36]) to visualise the content. Note many CIDs are in multiple sub-categories, and total counts include this duplication (i.e. the 5695 AgroChemInfo count corresponds with fewer unique CIDs, see below). An interactive version embedded in an RMarkdown file is available as Additional file 1, the interactive plot plus code and example file is also available on the ECI GitLab pages [37, 38]
