Build adjustable graph for Wix webpage

I need to build graph, which can be easily updated on Wix.com webpage.
It should have similar functionalities like this one: https://www.conseq.cz/investice/prehled-fondu/conseq-realitni-czk

Might be using chart.js or https://www.highcharts.com/products/highcharts/

Crutial is to have ability to easily add datapoints.
