Detailed Description

Real-Time Data Streaming and Animation.

This gallery example demonstrates real-time data streaming capabilities using Plotly.cpp's extendTraces functionality. It creates a live-updating sine wave that streams data points continuously, showcasing dynamic visualization techniques for time-series data.

Features demonstrated:

• Real-time data streaming using extendTraces API
• Live plot animation with controlled frame rate
• Rolling window data display with maximum point limits
• Thread-safe plot updates in real-time loops
• Continuous mathematical function generation (sine wave)
• Browser connection monitoring for graceful termination
• High-frequency data updates (20 Hz) for smooth animation

Technical concepts:

• Plotly.js extendTraces equivalent implementation in C++
• Time-series data streaming with automatic old data removal
• Multi-threaded visualization with controlled timing
• Memory-efficient streaming with bounded data windows
• Real-time mathematical function evaluation

The streaming visualization creates a smooth animated sine wave that continuously scrolls across the screen, demonstrating the capability to handle live data feeds and sensor readings in real-time applications.
