Implements the 2D visualization of chemical structures.
StructureView2D visualizes chemical structures in the form of 2D structure diagrams (also known as skeletal formulas [WSKF] or structural formulas [WSTF]) that allow for an easy perception of important chemical characteristics like constitution, connectivity and stereochemistry.
Graphical details of the generated structure diagrams (colors, fonts, line-widths etc.) are configurable on a StructureView2D instance level by control-parameters and on a visualized data object level by setting appropriate Chem::Atom, Chem::Bond or Chem::MolecularGraph properties. Properties of the visualized data objects have a higher priority than equivalent control-parameters of the StructureView2D instance and properties of Chem::Atom or Chem::Bond objects override corresponding properties of the parent Chem::MolecularGraph instance.
