It is easy to visualize genomic inversions with a syntenic dotplot. Since syntenic regions appear as colored lines in the syntenic dotplot generated by SynMap, inversions are seen when a syntenic line has a discontinuity or break, and there is an adjacent line with an opposite slope (e.g. a positively sloping line has a break and adjacent to it is a negatively sloping line).
In the example shown here, SynMap colored the syntenic lines green if they have a positive slope and red if they have a negative slope. This plot has a nearly continuous green line starting at the origin in the lower left and sloping to the upper right.
