Sankey Diagram by Mike doesn't load?


I’m trying to review Mike’s sankey diagram visualization: https://beta.observablehq.com/@mbostock/d3-sankey-diagram

and it doesn’t load. The only message on the developer console is

The Content-Security-Policy directive ‘prefetch-src’ is implemented behind a flag which is currently disabled.

which is coming from d3-sankey-diagram:1, the current page.

Any hints from anyone?


Hi @jjimenez.

What browser are you using and what version is it? Ditto for your OS? Does it work in a different browser?


this is in chrome Version 69.0.3497.100 (Official Build) (64-bit) on a mac. Safari and firefox seem to work fine. And somehow it is totally my issue. When I open an incognito window it works just fine. I’ll troubleshoot some more.


relaunching my browser (after an update) seems to have solved the problem.
