Re: change custom visual name

You can change the display name of a visual in the pbiviz.json file.  The displayName property changes what is see by uses when they hover over your visual in the Visualizations list.

{
  "visual": {
    "name": "snazzyTable",    "displayName": "Snazzy Table",    "guid": "PBI_CV_B9C6C6C7_9583_4BF9_B2E0_9CE157681851",
    "visualClassName": "SnazzyTable",
    "version": "1.0.0",
    "description": "",
    "supportUrl": "",
    "gitHubUrl": ""
  }

Is this what you are after?
