This is a big instance of the TSP. Lots of points and edges to draw in a rendering of the tour. But the three.js JavaScript 3D library is up to the task. My 2017 iMac has an 8GB graphics card. More than enough for the StarHorse point set.
It's fun to zoom and pan around the tour in an interactive display, but the data file is too large to post on the webserver. Sorry. What we can offer are several screen shots and video recordings. As usual, the points and edges are colored in tour order; the hue of each point/edge represents its position in the tour.
Rotate the full tour to have a look at its global structure.
Trace the tour, advancing 100,000 stars at a time and displaying 10,000,000 edges.
The tour is rendered with the three.js JavaScript 3D library.
We thank Michael Boyle for suggesting the use of color hue to indicate the order stars appear in our solution.
