3D Graphs by Matrix builds a directed graph of chords in 3D: each arrow goes from one chord to another, and the arrows come from a chord matrix or from the progressions you type. It's free and opens without an account.
In the matrix, each cell you turn on is an arrow from the column's chord to the row's chord. You can also type progressions with chords separated by commas and transpose them by semitones or to all twelve keys.
