title: How to visualize NodeJS .cpuprofile
body: <p>I use v8-profiler to profile my NodeJS app. It generates a .cpuprofile file.</p>
  
  <p>I used to be able to visualize the content of the file with Google Chrome built-in DevTools. However, Chrome recently changed the file format for profiling results and Chrome is no longer able to read .cpuprofile files.</p>
  
  <p>Note: My goal is to see the call tree and bottom-up. I do not care about flame chart.</p>
  
  <p>Thanks.</p>
