i cloned your repository and just launched chromium-browser index.html from ./examples

There is a longer explanation of Access-Control-Allow-Origin, but it boils down to the fact that you need an http server rather than just rendering an html file. In the root igraph directory, run python -m SimpleHTTPServer, and then go to localhost:8000/example. This allows the html to make requests for external files.
