i started learning about git architecture and wanted to know why do we only have 1 root tree for 1 commit always. we have multiple subtrees or blobs inside the root tree right but why is the root tree even there when the we can replace root tree with commit itself. Commit being directly related to subtree and blob. Like i said i just started learning it and am just looking for an answer which have been bugging me for a while.

I want to understand how I can showcase the pipelines I have built using Python scripts that pull data from different APIs, transform it to meet business requirements, and store it in BigQuery for further analysis. I want clients to be able to see my work, ideally for continued engagement or retention. A visual representation is usually the most effective way to present work, but I’m not sure how to do that for data pipelines. These pipelines process billions of rows of datasets with daily updates for a marketing agency that works with several large tech companies.
