I’m very new to data visualization, especially with D3 tools, and I’ve hit a very frustrating roadblock. I’m trying to visualize a database of community resources using a radial cluster tree diagram. My main challenge has been formatting my hierarchical data correctly and uploading it to Observablehq. To this poitn I have still not been able to visualize my data after days of trying.
Here’s what I’ve tried:
- I’ve spent countless hours trying to format my data, both in .csv and .json formats.
- Every time I attempt to upload these files to Observablehq, I encounter errors like “root errors” or “chart = RuntimeError: data is not defined”. My Radial Tree has never once appeared.
- I’ve sought help from ChatGPT and watched numerous tutorials, but I’m still struggling to grasp the exact steps.
I understand that I might be missing some fundamental steps or concepts, given my limited coding experience. I’m hoping that a kind soul could:
- Point me to a comprehensive, step-by-step tutorial suitable for a beginner…I’m talking baby steps
- Offer insights or tips on how to format hierarchical data correctly for a radial cluster tree diagram.
- Provide guidance on uploading data to Observablehq without errors from excel (which I am most comfortable with).
