👉 Collotype is a type of graph paper that consists of multiple sheets of paper arranged in rows and columns. Each sheet represents one or more graphs, with each line representing an element of the graph. The sheets are typically arranged in a grid pattern, with each row representing a column and each cell representing an element of the graph. Collotypes can be used to create complex diagrams by adding multiple lines to one sheet, making it easier to visualize the relationships between elements.
