This is great. My one suggestion would be to include some one click way to jump to visualisations of a handful of examples. Granted you've got placeholder text but a) users have to type that in both boxes to actually see it; b) it's just one example; c) often people will be curious to see a repo for their favoured tech, so a few would be handy and lastly d) people won't necessarily know the repo author name off by heart so a simple way to have people use it will get them trying this out much more effectively Something like a short series of links that populates got a repo each would be ideal.
