Today's Mathtober prompt is "Chord". Instead of the musical definition, I'm going with mathematical, which is roughly a line between two points on a circle. In my #inkyDays drawing, I'm adding a new circle at one point of the last chord and adding a new chord to the new circle, forming what looks like a string of beads.
