I'll create an interactive React Flow project that teaches you the fundamentals through hands-on experience! This will include draggable blocks with different functions, customizable parameters, and visual data flow.

This interactive React Flow learning project demonstrates all the key concepts you wanted to explore:

Key Learning Features:

1. Drag & Drop Blocks

• Sidebar Library: Different block types with descriptions
• Visual Feedback: Color-coded blocks for different functions
• Easy Placement: Drag from sidebar to canvas

2. Block Types & Functions

• Input Nodes: Generate numeric values
• Math Nodes: Perform calculations (add, subtract, multiply, divide)
• Text Nodes: Process text (uppercase, lowercase, reverse, length)
• Condition Nodes: Evaluate conditions (greater than, less than, equal)
• Output Nodes: Display final results

3. Customization

• Properties Panel: Click any block to customize its parameters
• Real-time Updates: Changes immediately affect the flow
• Visual Feedback: See input/output values on each block

4. Data Flow & Chaining

• Animated Connections: Visual representation of data flow
• Automatic Processing: Data flows through connected blocks
• Real-time Updates: Changes propagate through the entire chain
• Visual Input/Output: See how data transforms at each step

How to Use:

1. Drag blocks from the sidebar to the canvas
2. Connect blocks by dragging from the right handle to the left handle of another block
3. Click blocks to open the properties panel and customize them
4. Watch the data flow - values automatically update through connected blocks
5. Experiment with different combinations and operations

React Flow Concepts You'll Learn:

• Custom Node Types: How to create specialized nodes
• Handle Positioning: Input/output connection points
• Data Flow Management: Passing data between nodes
• Event Handling: Node clicks, connections, drag & drop
• State Management: Updating node data and triggering recalculations
• Visual Feedback: Animated edges and real-time updates

Try building different flows like:

• Number → Math → Math → Output
• Input → Condition → Output
• Input → Text → Text → Output

Great question! Let me explain how the blocks are currently running and show you how to add manual execution controls to better understand the flow.

How Block Execution Works:

Current Behavior (Auto-Run Mode):

1. Automatic Execution: Blocks run automatically when:

   • You connect two blocks
   • You change a block's properties
   • You add a new block

2. Data Flow Process:

   • Starts from input nodes (they generate their own values)
   • Flows through connected blocks in sequence
   • Each block processes its input and produces an output
   • Output blocks display the final result

New Manual Control Features:

1. Auto Run Toggle: Turn off automatic execution to control when blocks run
2. Manual Run Button: Click "Run Flow" to execute all blocks once
3. Clear Button: Reset all outputs to see the flow from scratch
4. Speed Control: Adjust how fast the execution happens
5. Visual Indicators: Blocks glow and pulse when they're executing

Execution Flow Example:

Try These Experiments:

1. Turn off Auto Run and manually step through execution
2. Change the speed to "Slow" to see each block execute
3. Use the Clear button to reset and run again
4. Watch the visual indicators as blocks process data

The blocks are now much more interactive and you can see exactly how data flows through your React Flow network!
