I made this little webapp with data from DBpedia. It uses Sparql for the queries and uHTML for the rendering. See github.com/danielbeeke/dbpedia-influence-view for the code.
This is for Drupal sites. It has a strong firewall (csf) and it has a lot of crawler detections on the nginx configurations. It checks the load and when on high load it blocks the crawlers.
Of course there are counterexamples but most websites aren't using SVG. Out of the Alexa top 20 only live.com is using svgs everywhere where they make sense and only yahoo.com is using them in some parts of the website.
