Mapping visualization is broken for all ontologies in BioPortal

[jvendetti]

Steps to reproduce:

1. Navigate to the Mappings page
2. Select any ontology from the dropdown
3. Select the Visualization radio button

The result is a blank screen and the following error in the developer console:

Uncaught TypeError: Cannot read property 'scale' of undefined

Hi all,
Is there any news about this? , it seems that this project (biomixer) is no more supported.
