Metadata visualization for sequential data: Missing sequence index

[npatki]

Environment Details

• SDV version: 1.3.0 (latest)
• Python version: Any
• Operating System: Any

Error Description

If I have sequential metadata, I can use the new single table visualize method to see the columns (see API).

When I use this, I see that the visualization correctly shows me any primary keys and sequence keys. However, it does not include the sequence index which an equally important part of my metadata.

Steps to reproduce

You can reproduce this with the demo data. The column Date is the sequence index.

from sdv.datasets.demo import download_demo

real_data, metadata = download_demo(
    modality='sequential',
    dataset_name='nasdaq100_2019'
)
metadata.visualize()

Output:

Expected Behavior

No matter what parameter is selected, the bottom section of the visualization should include all 3 valuess:

• primary key
• sequence key
• sequence index

Note that all the concepts are optional, so if any of them are missing, they do not have to show up. Also see #1543, to make sure that these concepts show up in a single box, without any horizontal sub-dividers.
