In this post, we’ll walk through the process of creating a simple application that can crawl the web starting from a given URL, and visualize the hyperlinks it finds as an interactive web graph. We will accomplish this using pure JavaScript and the MindFusion.Diagramming library, which provides the powerful features needed for graph creation, layout, and interaction.
A frequent requirement for many kinds of diagrams is to keep their underlying graphs acyclic. If your application lets users draw diagrams interactively, you could prevent forming a cycle by rejecting new link between a pair of nodes that are already connected by a path.
Continue readingIn this blog post we will demonstrate how you can implement methods that save and load part of the information that a diagram renders into JSON format. The Diagram class has built-in toJson and fromJson methods. They serialize completely the diagram with every detail so you can restore it completely, exactly the way you see it. What we are going to do is write custom save and load methods that use only part of the information – namely the size and location of nodes and links as well as their text.
In this blog post we look how you can create TableNode that render their cells following the logic of a list view: the tables have as many table columns and rows as needed in order to fit their content. The width of each column is fixed. When necessary, tables can be scrolled vertically. This is the final result:
In this blog post we are going to look at the steps required to run the MindFusion Diagramming library for ASP.NET MVC under a Linux server.
