Creating a custom vega-template dvc with tool-tip images

[ayman-saleh]

Hello,

I created a vega plot that is a scatter plot with a tool-tip when you hover over a data point to look at an image.

I want to embed this vega plot into dvc, but it seems that I have to create a dvc template.

In order to render the base64 encoded image when you hover over a datapoint, you need to read data with the key image otherwise it will not render correctly.

How do i reference a created template within dvc.yaml under plots?

If you are using the top level plots field in your dvc.yaml, you would specify the custom template in

plots:
  - <data series source>
    template: <template name>
    ...

(see the example in the docs: https://dvc.org/doc/user-guide/experiment-management/visualizing-plots#visualizing-plots)

For templates stored in .dvc/plots (default location for custom templates), the path and the json extension are not required. Otherwise, you would specify path + file extension to your template (where the path is relative to the dvc.yaml location)
