# Data Visualization
|
|
|
|
## When to Use
|
|
|
|
Use this skill when:
|
|
- Adding charts (donut, pie, bar, line, area) to a dashboard or analytics page
|
|
- Displaying KPI/metric stat cards with trend indicators
|
|
- Building a dashboard layout with mixed chart types and summary cards
|
|
|
|

|
|
|
|
## Step 1 — Determine the visualization type
|
|
|
|
Identify what the user needs:
|
|
|
|
- **Donut / pie chart** — categorical breakdown (e.g. issue types, status distribution)
|
|
- **Bar chart** — comparison across categories or time periods
|
|
- **Line / area chart** — trends over time
|
|
- **Stat card** — single KPI metric with optional trend indicator
|
|
- **Combined dashboard** — stat cards + one or more charts
|
|
|
|
If unclear, ask:
|
|
|
|
> "What data should the chart display, and would a donut chart, bar chart, line chart, or stat cards work best?"
|
|
|

|
|
|
|
## Step 2 — Install dependencies
|
|
|
|
All chart types in this skill use **recharts**. Install once from the web app directory:
|
|
|
|
```bash
|
|
npm install recharts
|
|
```
|
|
|
|
Recharts is built on D3 and provides declarative React components. No additional CSS is needed.
|
|

|
|
## Step 3 — Choose implementation path
|
|
|
|
Read the corresponding guide:
|
|
|
|
- **Bar chart** — read `implementation/bar-line-chart.md` (categorical data)
|
|
- **Line / area chart** — read `implementation/bar-line-chart.md` (time-series data)
|
|
- **Donut / pie chart** — read `implementation/donut-chart.md`
|
|
- **Stat card with trend** — read `implementation/stat-card.md`
|
|
- **Dashboard layout** — read `implementation/dashboard-layout.md`
|
|

|
## Verification
|
|
|
|
Before completing:
|
|
|
|
1. Chart renders with correct data and colors.
|
|
2. Chart is responsive (resizes with container).
|
|
3. Legend labels match the data categories.
|
|
4. Stat card trends display correct positive/negative indicators.
|
|
5. Run from the web app directory:
|
|
|
|
```bash
|
|
cd force-app/main/default/webapplications/<appName> && npm run lint && npm run build
|
|
```
|
|
|
|
- **Lint:** MUST result in 0 errors.
|
|
- **Build:** MUST succeed.
