This visualization creates a square matrix of pink cells, where each cell represents an edge between two vertices from a CSV dataset. The x- and y-axes list the unique vertex IDs from the edge list, sorted in ascending order, with axis labels drawn along the top and left. For each edge in the dataset, a pink square is plotted at the intersection of its source and target vertices. Hovering over a square highlights it in aqua and displays the corresponding edge coordinates as text. The matrix is enclosed in a black border with grid lines drawn at each vertex position, making the adjacency structure of the network visually apparent.
