Here are the classes, structs, unions and interfaces with brief descriptions:

CWMG_Anim	A static utility class for performing animations
CWMG_Axis	The axis used in WMG_Axis_Chart for X / Y axes, as well as secondary Y axis in Dual Y axis charts
CWMG_Axis_Graph	Used for all charts that use axes to position data
CWMG_Bezier_Band
CWMG_Bezier_Band_Graph	Class used for creating a bezier band graph, which is a collection of textures procedurally generated from bezier curves
CWMG_Change_Obj	Class used for property change tracking management to for example only refresh parts of a graph based on properties that affect only that part of the graph
CWMG_Compute_Shader	Class used to represent a texture that is procedurally generated using a Compute Shader
CWMG_ComputeLineGraph_Data	Helper class used to hold data for area shading when WMG_Series::areaShadingUsesComputeShader = true
CWMG_Data_Source	This defines a data source which can be used with WMG_Series, WMG_Pie_Graph, or WMG_Ring_Graph
CWMG_EnumFlagAttribute	Helper class for drawing Enums in custom Unity Editor inspector windows
CWMG_Enums	Static enum definitions used by various classes
CWMG_Events	Defines click and hover events for graphs that inherit WMG_Graph_Manager
CWMG_Graph_Auto_Anim
CWMG_Graph_Manager	The base graph class from which most graphs are derived
CWMG_Graph_Tooltip	The tooltip for axis graphs when WMG_Axis_Graph::tooltipEnabled = true
CWMG_Grid	The grid class used for creating quadrilateral or hexagonal grids
CWMG_GUI_Functions
CWMG_Hierarchical_Tree	A class used for creating hierarchical tree type graphs
CWMG_Image_Custom_Mat	Class used in place of Image component for series area shading rectangles to ensure that it works with Unity UI Masking such as within a ScrollView
CWMG_Legend	The legend used for pie graphs and axis graphs
CWMG_Legend_Entry
CWMG_Link	The link class primarily used for the lines in line series in axis graphs
CWMG_List
CWMG_Node	The node class primarily used to create the points / bars of axis graphs
CWMG_Pie_Graph	Class used for creating pie graphs
CWMG_Pie_Graph_Slice
CWMG_Radar_Graph	Class used for creating radar graphs
CWMG_Random_Graph	A class used to create random graphs
CWMG_Raycaster	Class used in place of GraphicsRaycaster for generating UI mouse events that work with non-squares (using alpha pixel values of textures)
CWMG_Raycatcher	Class used to indicate this object will respond to rays cast by WMG_Raycaster
CWMG_Reflection	Static utility class for using C# reflection functions, used in WMG_Data_Source
CWMG_Ring
CWMG_Ring_Graph	Class for creating ring graphs or pie graphs
CWMG_Series	Used to display a series of data in WMG_Axis_Graph Charts
CWMG_Text_Functions
CWMG_Util	Static utility class for performing miscellaneous functions such as data generation functions
