About the Line Chart design

Four solid discs mark the turns of a single zigzag stroke, and each one is wide enough to swallow the ends of the bars running into it. The line climbs, drops through a shallow V, then climbs again to the highest disc at the right, ending there with no axis or grid under it. The two rising stretches run at nearly the same angle, while the short fall between them drops steeply, one sharp dip in an otherwise steady rise.
