WebManhattan plots are widely used in genome-wide association studies (GWAS). The idea is to represent many non-significant data points with variable low values and a few clusters of significant data points that will appear as towers in the plot.

WebManhattan plot is very useful to check the overview of our sumstats. But if we want to check a specific genomic locus, we need a plot with finer resolution. This kind of plot is called regional plot. It is basically the Manhattan plot of only a small region on the genome, with points colored by its LD r2 with the lead variant in this region.
