Integration of anycharts treemap using looker custom visualization

Hi Team,

I am reaching out to inquire about the process for integrating our custom visualization into Looker. Below are some specific queries for which I am seeking guidance:

  1. I am currently utilizing AnyChart treemap and aim to incorporate this chart into our Looker dashboard. Could you please provide the necessary steps to achieve this integration effectively?
  2. I am currently managing three distinct files for various purposes:
    • manifest.json: This file defines the visualization metadata and configuration. It includes references to external libraries (such as AnyChart, for example: "Main": "https://cdn.anychart.com/releases/8.12.0/js/anychart-treemap.min.js") and specifies the main HTML file path.
    • manifest.lkml: Specific to Looker's internal development environment.
    • anychart.html: This HTML page contains the code for the visualization.
      Upon reviewing the repository at https://github.com/looker-open-source/custom_visualizations_v2, I noticed that there is no need to create an HTML page. Instead, we can directly pass the JavaScript code, and Looker will handle the rest and looker workspace is also not allowing to save the html file.

Given the above points, could you kindly advise me on the recommended approach to proceed further along with some kind of example that uses external libraries for visualization?
