BLAST a sequence and get a tree and a map

I've updated the BLAST a sequence and get a tree tool described in a previous post to output additional details, such as a list of the sequences used to build the tree and some basic metadata (such as the taxon name, name of any associated host, publication, and geographic coordinates). If the sequences are geotagged, then you will also see a little map showing the localities. As ever, all this relies on SVG, so if you're browser doesn't support that out won't see much.

The example below is for the sequence EU399074, which falls in a cluster of "dark taxa"; in this case, DNA barcode sequences that haven't been properly labelled.
