Today, METAL's Highway Data Examiner was enhanced in two ways:

1) The Vertex Closest Pairs search algorithm visualization now searches for both the closest pair and the most distant pair of waypoints in the graph.

2) The "Option 1" search bar on the "Load Data" panel now matches filenames as well as descriptions.

A new version of HDX has been installed into production today.  This version implements some new algorithm visualizations, has support for conditional breakpoints, and has many bug fixes and UI improvements.

The production HDX has a new feature to load a graph on startup with the load= query string parameter.  For example

https://courses.teresco.org/metal/hdx/?load=AND-region-collapsed.tmg (https://courses.teresco.org/metal/hdx/?load=AND-region-collapsed.tmg)

would load the Andorra graph without bringing up the Load Data panel.

There is also a noav QS parameter that will bypass the Algorithm Visualization selection panel.  It can be used by itself, or in conjunction with the load QS parameter.

Please let me know if you notice that anything has been broken with this update.

Another QS parameter was added to HDX, units= can specify miles, km, ft, or meters.  Your choice will be remembered in a browser cookie and remain in effect until you load HDX with a different
Code: [Select]
units= value.

Issue https://github.com/TravelMapping/EduTools/issues/324 has been opened to reflect the intent to allow this to be changed through the site UI at some point in the future.

A new version of METAL's HDX is almost ready, with a new user interface, a few new algorithms, and various other enhancements.  For now, it can be accessed at https://courses.teresco.org/metal/hdxt/

Is it possible to get back to the start dialog without reloading the url?

The manual needs to be updated once it will be live, e.g. https://travelmapping.net/devel/manual/syserr.php#nearmisspoint

After clicking [Visualize] (even if just Visualize Graph Data Only) there will be a [New Graph] button @ top right.

Still a few things that need fixing, but I have replaced the default production HDX version at https://courses.teresco.org/metal/hdx/ with version 3, the one with this past summer's enhancements.  The previous production version will remain indefinitely at https://courses.teresco.org/metal/hdx2/ but I do not have plans to maintain it.

Please report any bugs and offer any suggestions using GitHub Issues at https://github.com/TravelMapping/EduTools .  Have a look through existing Issues first, though, as there are plenty of things already reported as problems and requested/planned as new features.
