Layout Pattern

Venn

Show overlap among 1 to 7 sets using one flat list of short labels. The list order identifies the sets; no overlap values are implied. One to four sets have labels inside the circles, and five to seven beside them. Long labels, nested entries or unsupported counts retain the complete list with a finding instead of shrinking the text.

How to Use It

Show overlap among 1 to 7 sets using one flat list of short labels. The list order identifies the sets; no overlap values are implied. One to four sets have labels inside the circles, and five to seven beside them. Long labels, nested entries or unsupported counts retain the complete list with a finding instead of shrinking the text.

Preview + source

Explore this layout

Show how a few sets overlap, one short label per set; say in the title what the overlap means.

All people, quotations and business figures in these examples are illustrative.

This prepared preview and the OPF describe the same example. Region outlines show measured allocation; toggling them does not change the slide.

Regions, in reading order

This layout is one list of 2 regions, declared once. The list runs as a column; a split nests a list that runs the other way. Each size is a share of its parent’s width (row) or height (column).

Schematic of the list: each box is drawn in proportion to its size; an auto entry gets a fixed band. Dashed boxes are heading regions.

Column, stacked, top to bottom. No anchor is written on the layout: body regions start at the top unless they set their own.

  1. 1titleauto

    auto, the height the content needs

    Heading region: holds the slide’s title, with its tag and subtitle. It takes a size and no content rules.

How automatic composition differs

Try dynamic composition

Explore how a text slide reflows as you change its content and shape. These examples use OPF’s shared composition rules; the copied document includes your choices.

Let the content find its spaceStart with the decision. State what the audience should understand or do.Show the evidence. Give each supporting idea enough space to be read.Make the next step clear. Keep the action specific and easy to remember.

All sample text fits within its content boxes.

Chevrons

Show 1 to 8 stages that follow one another, each leading into the next. Write one short list entry per stage, in order; a word or two reads best inside a chevron.

Groups Of Items

Cycle

Show 2 to 8 steps that repeat, where the last leads back to the first (a review loop, a product lifecycle, a feedback cycle). Write one short list entry per step, in order; the first is drawn at the top and the rest clockwise, with an arrow from each to the next.

FAQ

Answer the questions an audience is likely to ask. Pair each question with a direct answer and group related questions together.

Groups Of Items

Hierarchy

Show a classification or work breakdown with 1 to 8 short entries. Use one list: the first entry is the level-zero root and each child sets its zero-based level. Keep parents before children and do not skip a depth. Unsupported forests, jumps, descriptions or long labels retain the complete list with a finding instead of changing relationships or shrinking text.

Inverted pyramid

Show 1 to 8 levels narrowing from the broad top (the many, the starting pool) to the tip below (the selected few, the result). Write one short list entry per level in top-to-bottom order. Export uses editable native shapes.
