Not quite sure what you mean by putting an HTML-like border around each 
subgraph. However, if you would accept the type of
of border that gets placed around clusters, the trick is to wrap each 
graph in a cluster. That can be done as follows:

   ccomps -x data.dot | gvpr -c 'BEGIN{$tgtname="cluster"}N[1]E[1]' | 
dot | gvpack -g | neato -s -n2 -Tsvg > tree.svg

You can modify the gvpr script to change the display attributes, such as 
color and width, of the border.
