Tool to show DNA sequence and allowing upload of own graph data Background

We want to be able to load (or request) data for a genome including the sequence and gene annotation (bacteria). Then, we want to load our own annotation which should be displayed as a line plot:

position score
1        5
2        6
etc.


Where each position corresponds to the position in the genome (i.e. FASTA).
Something like this: 



Question

Is there a tool that can load a genome sequence, gene annotation, and a position ~ score file, which can be displayed as a line plot?
You can use UCSC genome browser, which supports custom genome sequence and annotation. Specifically, one needs to create a Track Hub to hold genomes and annotations. 

Here is an example: 


  http://genome.ucsc.edu/cgi-bin/hgTracks?hubUrl=http://zlab-trackhub.umassmed.edu/yfu/insects/hub.txt&amp;db=hub_129615_cl_v0.8.2


And here is the corresponding hub.txt file holding the metadata, and URLs to actual fasta, bigWig and bigBed files.
