Bars, lines, areas, pies, donuts, radar, histogram, scatter, bubbles, heatmaps, gauge, bullet, funnel, waterfall, treemap, candles, box plots, steps, rings, legend, axis, crosshair, polar area, pyramid, spectrum bars and win-loss strips, each drawn dot by dot. Ticks follow 1-2-5 steps and print as precisely as their step needs; a label row uses micro letters or the pixel font as a whole. Descriptions carry the data in numbers. Bad data panics.
