Help on custom graphs and charts creation/implementation


I am trying to figure out how to make this exact same chart/graph (Projection Chart - Endowus) with range slider controls, editable numbers on the range slider, math formula affecting the interactions and numbers of the chart.

Their website is also built on Webflow, the chart however is an embed and I’m not sure how they manage to build it that way.

Is this only possible with custom code or is there another way to build it where I may not be aware of? Would appreciate any help and advices I can get on this. Thanks!
