If you want to visualize the coverage on top of your genome, you can use Artemis. You load your genome and annotation in Artemis and a BAM file. There it will let you see not only globally but which regions are getting a higher or lower coverage.

IGV is a good choice.

 @Arjun Sahoo   I have  the exact same  suggestion as  Dong . Yes，IGV is a powerful tool to visualize the bam file to see the coverage profiling of you reads. You need input the refence genome fasta file,a bam file and an index file atthe same time.

Thank you all for your kind suggestions.

Qualimap will also do a very similar thing 

Or use bedtools `bedtools genomecov -bg -ibam   > out.bedgraph` to generate a per-base read count, which you can then feed into IGV or plot in R
