Struct ExpressionNode 

pub struct ExpressionNode {
    pub id: u32,
    pub expression: String,
    pub children: Vec<ExpressionNode>,
}

Represents a node in the expression tree for flow diagram rendering.

Fields

id: u32

Unique identifier for this node

expression: String

JSON string of this sub-expression

children: Vec<ExpressionNode>

Child nodes (arguments/operands that are operators, not literals)
