Abigail F. Olena,James G. Pattonw of extremal graph theory. What is the explanation for this phenomenon? We do not really know, so we offer three answers. (1) Being a string graph is a hereditary property. (2) String graphs are nicely separable into smaller pieces. (3) As in any geometric picture, one can discover several natural partial orders on a collection of strings.

Lei Qin,Md. Asraful Alam,Zhongming Wangwe show that the characterization is still incomplete by providing new . patterns not included in the previous characterizations. Moreover, we introduce an iterative method to create an arbitrary number of . patterns, thus proving that the set of minimal patterns that characterizes level planar trees is infinite.

We extend stress majorization by a weighting scheme which imposes radial constraints on the layout but also tries to preserve as much information about the graph structure as possible.
