title: Waterfall chart library like seen in jaeger
body: <p>I am trying to implement some performance monitoring tool for an internal library we are working on.</p>
  <p>We need to trace hierarchical spans/activities and output them in a waterfall chart (as known from Jaeger and the like) to visualize what is going on in our system.</p>
  <p>Unfortunately, it needs to run on Xamarin, so OpenTelemetry is not an option.</p>
  <p>What I am searching for is any component (javascript presumably) that can read some file format (json... whatever - in the end I can control the output myself and tailor it to be useable for some library) and show a performance waterfall chart.

  <p>Unfortunately, when searching for &quot;waterfall chart&quot; I only get these as a result:

  <p>Can anyone point me to the right direction, please?</p>
