Data Visualization Skill

This skill helps you create interactive data visualization apps with charts, data tables, and CSV handling.

When to Use

Use this skill when the user asks to:

• Create a dashboard, report, or data exploration app with data from any source
• Build charts, graphs, or data tables
• Visualize data from integrations (Stripe, Google Analytics, Linear, databases, etc.)
• Create an interactive analytics dashboard with filters and controls
• Build a reporting interface, metrics dashboard, or analysis report
• Explore or investigate a dataset with filters and drill-down
• Combine multiple data sources into a unified visualization

Key point: This skill handles data fetching internally. You do NOT need to query data first using other skills - this skill will use

searchIntegrations()

and

proposeIntegration()

to connect to data sources as part of building the app.

Example user requests

• "Create a dashboard showing my Stripe revenue"
• "Build a sales analytics dashboard"
• "Analyze my revenue data and present the findings"
• "Create a report explaining why conversions dropped"
• "Let me explore my customer data with filters"
• "Build a tool to browse and filter our product catalog"
• "Visualize this CSV file"

When NOT to Use

• The user is asking questions about data in chat (e.g., "How many Linear issues were closed last week?") - use

  query-integration-data

  skill
• The user simply wants to fetch/export/transform data without visualization - use

  query-integration-data

  skill
• The user is not asking for any visual output or web interface

Architecture

This skill uses the react-vite scaffold with backend conventions from the

pnpm-workspace

skill:

1. Create the artifact (

   createArtifact()

   with type

   data-visualization

   )
2. Install data-viz packages and patch CSS (chart colors + print styles)
3. Follow the contract-first backend flow from the

   pnpm-workspace

   skill (

   references/openapi.md

   ,

   references/server.md

   ,

   references/db.md

   )
4. Launch a design subagent (async) for the frontend
5. Implement API routes in the shared

   artifacts/api-server/

See

references/common-bootstrap.md

for the full step-by-step workflow.

IMPORTANT: Data visualization artifacts must use the design subagent workflow, not generateFrontend(). The reference files contain critical layout and styling specifications that only the design subagent can consume.

App Type Classification

Classify the user's request into one of three types. If ambiguous, default to Dashboard.

Dashboard (default)

Signals: "dashboard", "monitor", "KPIs", "metrics overview", "analytics", "track", "real-time"

Layout: KPI cards + grid of charts + optional detail table. Wide container (

max-w-[1400px]

).

Read these references:

• references/common-bootstrap.md

  — Setup and workflow

• references/dashboard-workflow.md

  — Steps 5-6, checklist, subagent template

• references/dashboard-layout.md

  — Grid patterns, KPI cards

• references/dashboard-controls.md

  — Split refresh with auto-refresh, date filters

Page structure: See

references/dashboard-page-structure.md

for composition skeleton

Analysis Report

Signals: "report", "analysis", "findings", "explain", "why is", "summarize", "readout", "review", "assessment"

Layout: Vertical narrative with embedded charts and written analysis. Narrow container (

max-w-[900px]

).

Read these references:

• references/common-bootstrap.md

  — Setup and workflow

• references/report-workflow.md

  — Steps 5-6, checklist, subagent template

• references/report-layout.md

  — Executive summary, section cards, recommendations

Page structure: See

references/report-page-structure.md

for composition skeleton

Dataset Explorer

Signals: "explore", "investigate", "browse", "filter", "drill down", "search data", "let me query", "look through"

Layout: Sidebar filters + central data table + reactive charts. Wide container (

max-w-[1600px]

).

Read these references:

• references/common-bootstrap.md

  — Setup and workflow

• references/explorer-workflow.md

  — Steps 5-6, checklist, subagent template

Handling Truncated Reference Files

IMPORTANT: When reading a reference file, the output may be truncated (indicated by

...[Truncated]

at the end). If truncated, note the last line number shown and re-read the file with

offset

set to that line number minus 10 (for overlap). Repeat until no

...[Truncated]

appears. Do not act on partial instructions from a truncated file.
