  Graph burning is a deterministic, discrete-time process that models how
influence or contagion spreads in a graph. Associated to each graph is its
burning number, which is a parameter that quantifies how quickly the influence
spreads. We survey results on graph burning, focusing on bounds, conjectures,
and algorithms related to the burning number. We will discuss state-of-the-art
results on the burning number conjecture, burning numbers of graph classes, and
algorithmic complexity. We include a list of conjectures, variants, and open
problems on graph burning.
