Every chart below is a real chart spec, resolved against the same data the explorer gives you and drawn by the same renderer that draws every chart on this site. Open one in the builder and it is yours to change.
Lines with rolling means, league average annotations, minimum volume gates, and season facets are all part of the spec language. If you can describe the chart, the builder can draw it.
