Accessing the HELM Monomer Library

This workflow retrieves the latest version of the HELM monomer library via the REST API for lib.monomer.org (as a JSON), and exemplifies several concepts:

---> Uses the 'GET Request' node to access a JSON string containing the HELM monomoer library via the web (lib.monomer.org)

---> Shows how the 'JSON path' and 'JSON to Table' nodes can be used to extract information from JSON-formatted data

---> Uses 'Renderer to Image' node for conversion of chemical structure to PNG; enables views in javascript nodes freely, or when packaged as metanode/WebPortal views.
