Hi All, Currently we are working on a new statistic and message tracing features for ESB 4.10.0 release. In both projects we are displaying collected data in a graph structure in the UI. Requirements for the graph library is given below.
1. At the start it should only display parent node 2. By clicking on a graph node, user can toggle its immediate children. 3. The user should be able to see more information about that node such as request count,max time etc. After searching for a suitable graph library we found out following 1. Most of the graph data visualizations are done using D3 java script library [1] 2. In DAS we are using VizGrammer [2] java script library which is a wrapper written on top of the D3 library. But it doesn't seem to have graph drawing ability yet. 3. Dagre java script library [3] can draw directed graphs but these are static digraphs. It also wraps D3 JavaScript library. Currently for both Statistic and Tracing projects we are using Dagre library. Statistic tree [4] generated for proxy configuration [5] and tracing of a message flow can be found in [6]. But the main problem of using this library is that graph is a static one and users cannot interact with it. For example I have written a dynamic tree structure using D3 in [7]. User can use click and double click events to interact with the tree. But since this is tree structure we cannot use it for our requirement. (i.e. in clone and aggregate mediators there are parallel flows which combines at the end). Is there a different way to implement this feature? Can we support this type of dynamic graphs using any of our internal library without using external libraries?
