You could just download IGV and then import the tracks. That would be quite simple and you should have IGV around anyway if you ever deal with NGS datasets.

Because we have a established genome browser based on GBrowse, this is pretty straightforward. I use wiggle2gff3.pl to convert bedGraph into wibs and a gff3 file pointing to those wibs. Then you'll use the GBrowse gff3 database for visualizing the tracks. It should be noted this way you reduced the resolution of the data, so it's only good for visualization but not quantitative analyses. The newer upgrade to this is to use BigWig perl module to handle these types of files.

The WashU Epigenome Browser developer is pretty responsive to help requests — I've always been able to fix my issues with his guidance. You can reach him through the WashU community site.
