Thanks for the feedback. I did not have the same issue, until I downloaded and tried with Chrome.
The issue is, I pretty sure, related to access restrictions. It is not allowed to just open a local file. And I can imagine that that is a good thing in general. The current .json is a data file. It is a real .json file in the sense that it contains only data:

{
  "$id": "1",
  "PathChartPoints": {
...
  },
  "PathName": "AIAPNorth"
}

Rewriting it to a javascript file should make things easier.

my data = {
  "$id": "1",
  "PathChartPoints": {
...
  },
  "PathName": "AIAPNorth"
}

It is not as clean. But it might circumvent all kinds of issues with access restrictions and the various ways the browsers deal with it. I will come back to this.

OK, let's try again. I tested with various browsers and got no issues. I have not yet tried Android or so. Also Trackviewer was updated for the output part
