Are there more examples for visual.ts, capabilities.json and R script for custom R Visuals?

v-viig thank you for the help. 

I'm still having trouble finding the interaction between Power BI fields added and the Rscript. 

I was wondering if you could point me in the right direction. 

Here is the plot I was to make with my custom visual: 

p = plot_ly(mtcars, x = ~wt, y = ~hp, z = ~qsec, color = ~am, colors = c('#BF382A', '#0C4B8E')) %>%
  add_markers() %>%
  layout(scene = list(xaxis = list(title = 'wt'),
                     yaxis = list(title = 'hp'),
                     zaxis = list(title = 'qsec')));

So to do this I did the following:

In capabilities.json I changed to this: 

{
  "dataRoles": [
    {
      "displayName": "CAR TYPE",
      "kind": "GroupingOrMeasure",
      "name": "Values"
    },
    {
      "displayName": "wt",
      "kind": "GroupingOrMeasure",
      "name": "Values"
    },
    {
      "displayName": "hp",
      "kind": "GroupingOrMeasure",
      "name": "Values"
    },
    {
      "displayName": "qsec",
      "kind": "GroupingOrMeasure",
      "name": "Values"
    }
  ],
  "dataViewMappings": [
    {
      
      "scriptResult": {
        "dataInput": {
          "table": {
            "rows": {
              "select": [
                {
                  "for": {
                    "in": "Values"
                  }
                }
              ],
              "dataReductionAlgorithm": {
                "top": {}
              }
            }
          }
        },
        "script": {
          "scriptProviderDefault": "R",
          "scriptOutputType": "html",
          "source": {
            "objectName": "rcv_script",
            "propertyName": "source"
          },
          "provider": {
            "objectName": "rcv_script",
            "propertyName": "provider"
          }
        }
      }
    }
  ],
  "objects": {
    "rcv_script": {
      "properties": {
        "provider": {
          "type": {
            "text": true
          }
        },
        "source": {
          "type": {
            "scripting": {
              "source": true
            }
          }
        }
      }
    }
  },
  "suppressDefaultTitle": true
}

And then I'm pretty sure I have to change visual.ts but I am unsure of what to change. 

Just making the changes above creates a bunch of errors in cmd line as you could guess. 

What step did I skip? 

Thank you
