A method of generating ElM2D scatter plots of compositional similarity is provided, which allows the results of querying the ElMTree application to be visualised in 2 dimensions. A matrix of ElMD distances is constructed between the query and the 100 most similar compositions returned by the ElMTree (fig. ). Alternatively, a list of compositions separated by commas may be input to the search box, and the matrix will be formed between these specific compostions only. This distance matrix is embedded to the plane using UMAP , with an interactive scatter plot and distance matrix generated using the plotly library . This allows ElMTree queries and datasets of compositions to be placed within chemical context, providing an intuitive representation of the chemical distribution.
