Seattle city energy app allows for links to be shown in the building scorecard view. The configuration for these are located in the seattle.json file. The data for the links are located in the cityenergy-seattle carto account.
Locate the "scorecard" block in the seattle.json file mentioned above. Set the links_table field with name of the dataset containing link data in Carto.
All data will be pulled from the Carto dataset that is set for the links_table field in the configuration file. New data will be automatically picked up the next time the web app is reloaded.
It's important to remember that any changes made to the seattle.json file will need to be "re-deployed" to be active in the production version. See the documentation in the main README file for how to deploy to production.
