# Visual System

Style name: Notebook Data Science Lab

## Core DNA

- One cream graph-paper page with a fine engineering grid filling the whole slide, with a soft page-corner curl.
- A row of black spiral binding rings running down the left edge with a thin shadow along the binding.
- Margin doodles hand-sketched in teal, navy and orange: scatter plots with fitted lines, hatched bell curves, node graphs, atoms, molecules, flasks and a mini color-swatch grid.
- Huge Japanese gothic headline drawn with a colored-pencil crayon hatch texture and slightly uneven edges.
- Headline color runs: deep-navy leading characters with a light-blue offset shadow, near-navy middle, vermilion orange final characters.
- One hexagon-ended outlined subline banner in navy type with small blue tally-mark ticks at both ends.
- White notebook cells with thin rounded borders in navy, teal and vermilion, each opened by a hand-drawn circled numeral at the top-left.
- Exactly three solid colored footer bars closing the cells, carrying white Japanese lettering.
- Solid navy block arrows and pencil-dashed connector lines as the only movement cues.
- One outlined rounded takeaway banner with a yellow highlighter swipe under the emphasized run, a washi tape strip at one corner and a tiny hand-drawn bar chart at the other.

## Intended Use

分析、モデル検証、仮説実験をテーマにしたスライドに使う。ノートブックセル、実験メモ、結果解釈カードで検証プロセスの手触りを見せ、手書きの思考過程が残った資料にする。

## Page Architecture

- One oversized headline.
- One subline banner.
- One dominant diagram occupying most of the body.
- Exactly three labels.
- One takeaway band.
- Three to six supporting icons that explain the diagram.

## Composition Grammar

- Cover: title page with the three bordered notebook cells previewing the three labels, spiral binding at the left, margin science doodles and the outlined takeaway banner with a highlighter swipe at the bottom.
- Problem: experiment log column marked at three vermilion-circled failed runs.
- Before-after: messy raw-data page resolving into a preprocessing cell and an interpretation cell.
- Three-step: three notebook cells as collect, run and interpret joined by navy block arrows.
- Loop: penciled hypothesize-experiment-measure-revise ring around a stack of trial cards.
- Checklist: washi-taped validation sheet with three oversized check rows and verdict tags.
- Roadmap: dashed pencil trajectory from baseline dot to vermilion target ring past three plotted checkpoints.
- Matrix: 2x2 hypothesis board ruled on graph paper with one teal marker-wash quadrant.
- Case: penciled research-day timeline with data pull, model run and result read-out markers.
- Recap: central summary cell with three stacked hand-written finding lines and science doodles.
