Turn a firm's financial statements into a directed, weighted bookkeeping graph — accounts as nodes, journal flows as edges.

Compute node- and edge-entropy on a bookkeeping graph and the Kullback–Leibler divergence between periods, then plot firms/periods to reveal structural change.
Graph Distance Analysis across Firms & Time (NetworkX)
Measure distances between firms' accounting graphs (peer similarity) and across time (structural change), including the Jensen–Shannon distance used for peer selection.
