I converted your text to this:

Using a text editor with find and replace:
First I replaced the comma with three spaces.
Then I replaced the newline character with four spaces + 0xffffff + newline character.
Then I put the header on it of frame xy hex real.
The fist line ends with -1 because that is the only point in the set that is only an anchor. It has no color, so I made it blank.
That opens just fine.
Not much to look at. It's just a section of an arc.
