Presentation Creator

Sentry Presentation Builder

Create interactive, data-driven presentation slides using React + Vite + Recharts, styled with the Sentry design system and built as a single distributable HTML file.

Step 1: Gather Requirements

Ask the user:

1. What is the presentation topic?
2. How many slides (typically 5-8)?
3. What data/charts are needed? (time series, comparisons, diagrams, zone charts)
4. What is the narrative arc? (problem → solution, before → after, technical deep-dive)

Data Assessment (CRITICAL)

Before designing any slides, assess whether the source content contains real quantitative data (numbers, percentages, measurements, time series, costs, metrics). Only create Recharts visualizations for slides where real data exists. Do NOT fabricate, estimate, or invent data to fill charts.

• Has real data → use a Recharts chart (bar, area, line, etc.)
• Has no data → use text-based layouts: cards, tables, bullet columns, diagrams, or quote blocks. Do NOT create a chart with made-up numbers.

If the source content is purely qualitative (narrative, opinions, strategy, process descriptions), the presentation should use zero charts. Recharts and Charts.jsx should only be included in the project if at least one slide has real data to visualize.

Step 2: Scaffold the Project

Create the project structure:

<project-name>/
├── index.html
├── package.json
├── vite.config.js
└── src/
    ├── main.jsx
    ├── App.jsx
    ├── App.css
    └── Charts.jsx

</html>

package.json

{
  "name": "PROJECT_NAME",
  "private": true,
  "type": "module",
  "scripts": { "dev": "vite", "build": "vite build", "preview": "vite preview" },
  "dependencies": { "react": "^18.3.1", "react-dom": "^18.3.1", "recharts": "^2.15.3" },
  "devDependencies": { "@vitejs/plugin-react": "^4.3.4", "vite": "^6.0.0", "vite-plugin-singlefile": "^2.3.0" }
}

vite.config.js

import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
import { viteSingleFile } from 'vite-plugin-singlefile'

export default defineConfig({ plugins: [react(), viteSingleFile()] })

main.jsx

import React from 'react'
import ReactDOM from 'react-dom/client'
import App from './App'
import './App.css'

ReactDOM.createRoot(document.getElementById('root')).render(<App />)

Step 3: Build the Slide System

Read references/design-system.md for the complete Sentry color palette, typography, CSS variables, layout utilities, and animation system.

App.jsx Structure

Define slides as an array of functions returning JSX:

const SLIDES = [
  () => ( /* Slide 0: Title */ ),
  () => ( /* Slide 1: Context */ ),
  // ...
];

Each slide function returns a <div className="slide-content"> with:

1. An <h2> heading
2. Optional subtitle paragraph
3. Main content (charts, cards, diagrams, tables)
4. Animation classes: .anim, .d1, .d2, .d3 for staggered fade-in

Do NOT add category tag pills/badges above headings (e.g., "BACKGROUND", "EXPERIMENTS"). They look generic and add no value. Let the heading speak for itself.

Navigation

Implement keyboard navigation (ArrowRight/Space = next, ArrowLeft = prev) and a bottom nav overlay with prev/next buttons, dot indicators, and slide number. The nav has no border or background — it floats transparently. A small low-contrast Sentry glyph watermark sits fixed in the top-left corner of every slide.

function App() {
  const [cur, setCur] = useState(0);
  const go = useCallback((d) => setCur(c => Math.max(0, Math.min(SLIDES.length - 1, c + d))), []);

  useEffect(() => {
    const h = (e) => {
      if (e.target.tagName === 'INPUT') return;
      if (e.key === 'ArrowRight' || e.key === ' ') { e.preventDefault(); go(1); }
      if (e.key === 'ArrowLeft') { e.preventDefault(); go(-1); }
    };
    window.addEventListener('keydown', h);
    return () => window.removeEventListener('keydown', h);
  }, [go]);

  return (
    <>
      {cur > 0 && <div className="glyph-watermark"><SentryGlyph size={50} /><span className="watermark-title">TITLE</span></div>}
      <div className="progress" style={{ width: `${((cur + 1) / SLIDES.length) * 100}%` }} />
      {SLIDES.map((S, i) => (
        <div key={i} className={`slide ${i === cur ? 'active' : ''}`}>
          <div className={`slide-content${i === cur ? ' anim' : ''}`}>
            <S />
          </div>
        </div>
      ))}
      <Nav cur={cur} total={SLIDES.length} go={go} setCur={setCur} />
    </>
  );
}

Step 4: Create Charts (Only When Data Exists)

IMPORTANT: Only create charts for slides backed by real, concrete data from the source content. If a slide's content is qualitative (strategies, learnings, process descriptions, opinions), use text-based layouts instead (cards, tables, bullet lists, columns). Never invent numbers, fabricate percentages, or generate synthetic data to populate a chart. If you are unsure whether data is real or inferred, do NOT create a chart.

If NO slides require charts, skip this step entirely — do not create Charts.jsx or import Recharts.

When real data IS available, read references/chart-patterns.md for Recharts component patterns including axis configuration, color constants, chart types, and data generation techniques.

Put all chart components in Charts.jsx. Key patterns:

• Use ResponsiveContainer with explicit height
• Wrap in .chart-wrap div with max-width 920px
• Use useMemo for data generation
• Color rule: Use the Tableau-inspired categorical palette (CAT[]) for distinguishing data series and groups. Only use semantic colors (SEM_GREEN, SEM_RED, SEM_AMBER) when the color itself carries meaning (good/bad, success/failure, warning).
• Common charts: ComposedChart with stacked Area/Line, BarChart, custom SVG diagrams
• Every data point in a chart must come from the source content. Do not interpolate, extrapolate, or round numbers to make charts look better.
