  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.
