Dash

When to Use This Skill

USE Dash when:

• Production dashboards - Building dashboards for business users
• Complex interactivity - Need fine-grained control over updates
• Enterprise requirements - Authentication, scaling, reliability needed
• Plotly ecosystem - Already using Plotly for visualizations
• Custom components - Need to extend with JavaScript/React
• Long-term projects - Dashboard will be maintained and extended
• Multi-user access - Multiple concurrent users accessing dashboards

DON'T USE Dash when:

• Quick prototypes - Use Streamlit for faster iteration
• Simple visualizations - Static reports may suffice
• No interactivity needed - Use static HTML/PDF reports
• Limited Python knowledge - Steeper learning curve than Streamlit
• Single-user tools - Jupyter notebooks may be simpler
