Cosmograph

A browser-based workspace for exploring graph and embedding data with filtering, search, timelines, public sharing and an optional AI Assistant. It accepts CSV, JSON, Parquet and Arrow data, and unsaved graphs can be explored without signing in.

Why I recommend it: Free for personal, educational and other noncommercial use; commercial use requires a paid license. Sign-in is required to save graphs and use the Assistant's limited free allowance.

Matplotlib

The open-source Python library for static, animated and interactive charts, with free plot-type galleries, tutorials, cheat sheets and a full API reference.

Why I recommend it: If you are learning data work, start here: the example gallery lets you copy a chart that already looks like what you need and adapt it.
