Hi, I want to create a custom radar plot using Vega spec by logging a `wandb.Table`. As a first step to this, I am first trying to create a custom chart using static data by copying the Vega spec defined here - [Radar Chart Example | Vega](https://vega.github.io/vega/examples/radar-chart/). The chart does not populate even for the static data and gives the following error - `TypeError: can't define property Symbol("vega_id"): Object is not extensible`. Can someone please help look into this? ---

Hi @sarda014, this is a known bug and we are actively working on a fix for this. Unfortunately, I don’t have a workaround at this time but I can attach you to the bug report so I can follow up as soon as we have a solution. ---
