If you want to deliver data to your customers you have two main options:

1. Build something custom in js

2. Use a drag and drop BI tool

(1) works if you are a front-end dev, but then it means the dev team need to own it forever, deal with customer requests etc

(2) means the data team can run it, but there's poor release management, and normally doesn't look good in your app

Evidence's version tries to hit the sweet spot: It's still written in code so you have version control and flexibility for customization, but it's SQL and Markdown so the data team can maintain it
