The d3.tsv
method makes an AJAX request for data. On most browsers, this won’t work locally due to the Same Origin Policy, which generally prohibits AJAX requests to file:///
urls.
To get an example that uses AJAX running locally, you’ll need a local webserver. If you have Python, running
> python -m SimpleHTTPServer
from the command line in the directory with your files will do it.
and if you are using python 3
> python -m http.server 9000
If you prefer node.js, try http-server.
