Style Presets: Side-by-Side Comparison

The four built-in presets — scientific, report, presentation, and minimal — each tune font sizes, spine weights, and tick density for a different rendering context. The differences only become obvious when the same data is drawn under each preset, so this gallery entry puts them in a 2×2 grid for direct comparison.

Pick the preset that matches the destination of the figure:

• scientific — journal / LaTeX articles (moderate fonts, thin spines)

• report — business reports at A4 page size (balanced spine weights)

• presentation — projected slides (bold typography, thick lines)

• minimal — landing pages / explanatory diagrams (chromeless)

Each panel below is rendered through dm.style.use(preset) inside a context manager (dm.style.context) so the presets do not leak into later examples.
