text: Bundling crossings is a strategy which can enhance the readability of graph
drawings. In this paper we consider bundlings for families of pseudosegments,
i.e., simple curves such that any two have share at most one point at which they
cross. Our main result is that there is a polynomial-time algorithm to compute
an 8-approximation of the bundled crossing number of such instances (up to adding
a term depending on the facial structure). This 8-approximation also holds for
bundlings of good drawings of graphs. In the special case of circular drawings
the approximation factor is 8 (no extra term), this improves upon the 10-approximation
of Fink et al. [6]. We also show how to compute a 92-approximation when the intersection
graph of the pseudosegments is bipartite.
