error loading topojson #364

Open eriktuck opened 2 years ago

eriktuck commented 2 years ago

The web application is returning an error when attempting to load topojson files. The file in question can be viewed here and appears to be formatted correctly (at least GitHub can render it in the browser). There are 340 features with one attribute per feature, so I don't think size is the issue.

Looks like our app needs to provide either the feature or mesh property: https://vega.github.io/vega/docs/data/#format

Can you try this example in the Vega editor: https://vega.github.io/editor/#/url/vega/N4IgJAzgxgFgpgWwIYgFwhgF0wBwqgegIDc4BzJAOjIEtMYBXAI0poHsDp5kTykSArJQBWENgDsQAGhAATJJhSoA2qHFIEcNCBricDTNJAAzNgCdkh1KEwBPHFvSY2ONqIlHjcBQzOOQAPwBIAC+Mr4ANtpYuPhEtBCY1HSMTAwQcGZQEphw4knZCATe4rKZYuIAtHA0BAIADADMxgBsLUgtjQCMACwtcADsAlA9SAKyI-UAnMY9XbIDXQBMABwEZkgA7gRQTAJwskurjVBdcAL9XUhIU1MDK-WDjSsDS7ItUPWyjVNIUHBdAjIHCUZyudySEIAXRCQA

The Vega editor link you provided is not showing any output for me. I tried a number of different "features" (objects, collections, geometries, arcs, GeometryCollection) but none worked.

That example doesn't have any visual output, sorry. If you open the JavaScript console you may see the Vega warning.
