Diagram
TsgcHTMLComponent_Diagram — render a node-and-arrow flow diagram as inline SVG, placing nodes at fixed coordinates and connecting them with labelled arrows, in Delphi, C++ Builder and .NET.
TsgcHTMLComponent_Diagram — render a node-and-arrow flow diagram as inline SVG, placing nodes at fixed coordinates and connecting them with labelled arrows, in Delphi, C++ Builder and .NET.
A flowchart component that emits a self-contained inline <svg>. Add nodes at X/Y coordinates, connect them with arrows, then read the HTML property.
TsgcHTMLComponent_Diagram
Inline <svg> nodes and arrows
Delphi, C++ Builder, .NET
Call AddNode for each box (with its position, colour and shape), wire them with Connect, then read HTML.

Nodes (TsgcHTMLDiagramNodes) holds the boxes; each TsgcHTMLDiagramNode exposes NodeID, Text, X, Y, Width, Height, Color and Shape.
AddNode(aID, aText, aX, aY, aColor, aShape) appends a node and returns it; aColor is a TsgcHTMLColor, aShape a TsgcHTMLDiagramNodeShape.
TsgcHTMLDiagramNodeShape offers nsRectangle, nsRoundedRect, nsCircle and nsDiamond.
Connections (TsgcHTMLDiagramConnections) holds the arrows; each TsgcHTMLDiagramConnection has FromNode, ToNode, Label_ and Color.
Connect(aFromID, aToID, aLabel_) draws a labelled arrow between two nodes referenced by their NodeID.
DiagramWidth, DiagramHeight and DiagramID size and identify the SVG; HTML returns the inline <svg> with arrows drawn behind the nodes.
