Plotly - Interactive Visualization

Plotly provides a wide range of interactive charts. Its "Plotly Express" API is designed for speed and ease of use with tidy DataFrames, while "Graph Objects" offers low-level control over every trace and attribute.

When to Use

• Creating interactive charts for web applications or Jupyter notebooks
• Visualizing 3D data (surfaces, scatter, mesh)
• Geographic maps (scatter on maps, choropleths) with Mapbox integration
• Financial charts (candlestick, OHLC)
• Exploring large datasets where zooming into specific regions is required
• Creating animations (time-series sliders)
• Building production-ready dashboards (via Dash)
