I have genomic positions in a tab delimited file as follows:

    Chr     Start   End
    2       10262865        11801950
    2       9637403          10927601
    2       25141434        27157396
    2       31181368        38044662
    2       127808684       129276101
    2       236957807       238896574
    2       237172736       238896574

 
**First I want to find overlapping segments within these genomic segments in the same file (edit)**. Then I wish to plot these such that the segments do not overlap on the plot.  Is there a tool that can aid in::
1 Finding overlapping regions within the same file
2. Visualising the segments in a non-overlapping manner? 

My attempts at plotting this in R results in the segments occupying the same position

using the tool developped for     https://www.biostars.org/p/336589 http://lindenb.github.io/jvarkit/Biostar336589.html
