manus-pptx

Author each slide as a <slide> element containing a required <background> child plus content elements like <text>, <shape>, <image>, <icon>, <table>, and <chart>. The markup is validated fail-fast and exports losslessly to pptx format.

Use the <chart> element with a type of bar, column, line, area, pie, donut, or scatter, plus categories, colors, and child <series> elements with numeric values arrays. Combination charts mix column, line, and area series with primary and secondary axes.

The syntax supports exactly 6 content elements (text, shape, image, icon, table, chart) plus a deck-level <design> block for canvas size, color variables, and font tiers. Tags or attributes not documented in the reference do not exist and must not be invented.

Validation is fail-fast with no silent fallbacks: every slide needs a <background> child, every content element needs a unique id, text/table/chart need a font, area shapes need a fill, and every chart series needs a resolvable color.

Yes, set dir="rtl" and lang on the <design> root for RTL decks, with dir overrides on text, table, p, li, and span elements. Weak-direction sequences like phone numbers must be wrapped in a single <span dir="ltr"> island inside RTL paragraphs.
