Graphical Visualization of XML data

I have an XML file that looks like this:

<rebase>
   <Organism>
     <Name>Aminomonas paucivorans</Name>
       <Enzyme>M1.Apa12260I</Enzyme>
         <Motif>GGAGNNNNNGGC</Motif>
       <Enzyme>M2.Apa12260I</Enzyme>
         <Motif>GGAGNNNNNGGC</Motif>
   </Organism>
   <Organism>
    <Name>Bacillus cellulosilyticus</Name>
       <Enzyme>M1.BceNI</Enzyme>
         <Motif>CCCNNNNNCTC</Motif>
       <Enzyme>M2.BceNI</Enzyme>
         <Motif>CCCNNNNNCTC</Motif>
   </Organism>
</rebase>

I want to visualize this XML data into a graphical format. The connectivity is such that a lot of organisms can contain common enzymes and/or motifs. I looked at d3.js but I dont think it has what im looking for. I was really excited with the visualization neo4j seems to provide but i will need to learn it from scratch. However I havent come across any good tutorials for importing or creating a graph in neo4j via XML datasets. I know in the world of programming anything is possible so I wanted to know the possible ways I could import my data (preferably using python) to a neo4j database to visualize it.
