A static site generator for data apps, dashboards, reports, and more. Observable Framework combines JavaScript on the front-end for interactive graphics with any language on the back-end for data analysis.
! Failed to initialize Framework cache. This may be a transient error loading data
| from external servers or downloading imported modules from jsDelivr; or it might
| be a network configuration issue such as a firewall blocking traffic. You can
| ignore this error for now and Framework will automatically try to download again
| on preview or build. If you continue to experience issues, please check your
| network configuration.
All the example files download, but when running npm run dev, the following error throws:
