I recently made a tool called Daigo. It's not as powerful as Power BI, Tableau or any OSS alternatives. But if you're looking to create a line chart or a dashboard from a SQL table or a CSV file, you may find Daigo a quick and easy solution.

It works with SQL databases and CSV file. Since it's an offline desktop app, it's free to use and you don't need to set up a server or upload data.
