Overlap heatmap for common compounds across the GHS data sources. Overlap here is quantified as intersection over union. Absolute numbers of compounds present in each source are given in the x axis. With the exception of the ECHA and SWA data sources (SWA uses ECHA as one of its own sources of classification), the heatmap indicates that other data sources contribute significant quantities of unique data, illustrating the benefit of collating toxicity data from multiple commensurate sources
