Why my CollapsibleTree code is not working?

Time:10-24

I was trying to mimic the CollapsibleTree Search code posted here by Patrick Brockmann (http://bl.ocks.org/PBrockmann/0f22818096428b12ea23) , and created a few files, the index html file and the other js files on my machine (in one folder) and it didn't work / or show me anything. I tried to keep the scripts with the online hyperlinks and didn't work too.

Please, what went wrong here?

Let's make a snippet and see. Well it seems to be working, just make sure your data (flare.json) is coming from the right place. Try from https://bl.ocks.org/PBrockmann/raw/0f22818096428b12ea23/fbfdb921528e8fd74b2de4231423d3a817bea0a4/flare.json or use hardcoded like I did because json isn't working here.
