One small change. A clearer slide.

Follow a slide from its first block to a complete composition. Compare each rendered step, inspect the OPF, then try the change yourself.

Each preview is a prepared render of its complete OPF example. The selected step records its render toolchain separately from the editable source.

Build your first slide

Start with one message, then add context, supporting copy and emphasis.

Build a two-region slide and see how automatic binding, explicit pins and track sizing relate.

Preserve six complete entries while adding sequence, columns and supporting detail.

Use honest magnitude bars, visible units and one shared dataset for the chart and table.
