[Question] Graphical representation of taxdumps

[fgvieira]

Is it possible to generate a graphical representation of a taxdump?

Most taxdumps are huge and impractical to represent graphically but, sometimes when testing, users work with reduced taxdumps that could be more amenable to a graphical representation. For example, something that would just convert taxdump to dot format and then to SVG:

awk -F"\t" 'BEGIN{print "digraph G {"} NR==FNR{print $3" -> "$1";"; labels[$1]=$1"\n"$5} NR!=FNR{print $1" [label=\""$3"\n"labels[$1]"\"];"} END{print "}"}' nodes.dmp names.dmp | dot -Tsvg > taxdump.svg

Alternatively, and to be able to work with the full taxdump, one could also think of an interactive html document similar to the one in Taxallnomy.

The network (tree) is too big to show.

Yes, if we try to represent everything, but the Taxallnomy link I linked above just represents parts of the tree at a time.
