Plotly offers more power and flexibility than chart.js and provides a much simpler API than D3 (it has D3 and webgl renderers).
The ecosystem is broad and includes React, Angular and other wrappers and language-interfaces for Python, Rust, Go, Scala and many others (incl Common Lisp).
If you start plotting a lot of data it can grow with you since it supports typed arrays and webgl rendering without undue boilerplate.
