Common (visualized) Graphical workflow implementation solution set

Today, I decided to write my own technical blog. I hope you will give me more advice.

1. VML implementation
What is VML? The following is a reprinted article:
VML (Vector Markup Language)
Is an XML Vocabulary originally developed by Microsoft. Currently, only ie5.0 and later versions support VML. You can use VML to draw vector images in IE. Therefore, some people think that VML implements the paint brush function in IE. The following describes the advantages of VML:
Based on XML standards
XML is recognized as a next-generation network markup language with infinite vitality. VML has inherent advantages in simple representation and is easy to expand.
Supports high-quality vector graphics display
VML supports a wide range of vector graphics features, which are based on the path described by connected straight lines and curves. Use two basic elements in VML: Shape and group. These two elements define the full structure of VML. Shape describes a vector graphic element, and group is used to combine these images so that they can be processed as a whole.
The VML Specification includes a large number of elements that support different vector graphics features. The following are the predefined graphic elements of VML:
L shape
L path
L line
L polyline
L Curve
L rect
L roundrect
L oval
L arc
L group
An image composed of text and can be integrated into HTML
Because VML uses simple text to represent an image, very few bytes can be used to represent a complex image. VML is compatible with HTML. By declaring the VML namespace and processing functions in HTML, you can use VML elements like other HTML elements to display images in the browser on the client. Most DHTML attributes and events can be defined in VML tags, such as ID, name, title, and onmouseover.
Supports interaction and animation
However, the VML function is not only a drawing, but also can embed text in the drawing, implement hyperlinks, and implement certain animation functions through the script language. VML Appreciation

It is the use of VML and above features to implement graphical workflows. Download the source code:
