A chord diagram has been plotted in Figure to depict this mutual relation between six most frequently reported perovskites and solvents. Chord diagram is a data visualization tool to represent connections between different entities. Such diagrams are useful in mapping out multivariate associations. Mapping these associations gives a broad overview of the interrelationship (flows, exchanges, etc.) between the connected entities. For the context of this work, the mapping displays how frequently the identified solvents and perovskites are observed together in the literature during perovskite synthesis. Zooming in further into these mappings unearths other information about the associations which we will discuss in the latter paragraphs. The data for a chord diagram is in the form of a matrix, such that the rows and columns have names of the desired entities (in our case, solvents, and perovskites) and the values in the matrix determine the width of the chords. This data is given in the supplementary material.
