Welcome to SysViz.org
SysViz is a Java-based graph building tool that lets you create graphs and/or mind maps in a quick and intuitive way, both online and completely free. Need to visualize the internal workflow within your company, the relationships between people who belong to a social network or your random thoughts on peanut butter? SysViz can help you with all of that - and more: we have developed a feature called Views, which helps you discover new information about a system, information of whose existence you may not even have been aware of. Once you have build your graph, activating one of these Views will automatically rearrange the nodes of the graph, thus providing you with an entirely new perspective on the system. You can switch between the various Views as you please and return to the original graph's layout at any time. The concept is probably best understood by testing it out!
Recent update information

Took me the better part of the week, but here it is: version 0.7.0 and the long overdue directed edges, delivered as promised, you're welcome. The next update will focus on user friendliness (such as tooltips and a rubberband feature) and will also add support for building trees and finite automata.

Applied a minor update (version 0.6.1). I played with the interface and fixed the minimap, which now works (almost) as intended. In case I (or one of you guys) do not run into any nasty bugs that require immediate attendence, the next update will elevate the tool to version 0.7 and is going to be all about edges and performance optimization. To those concerned: the special version for the 12th International DSM Conference in Cambridge can still be accessed here.

The new update is here (yay!), and it brings both good and bad news (mostly good though). Bad news first: still no directed graphs, sorry. I am aware that this is one of the main weak points of the tool at this point, and as such I will make sure to implement support for directed edges asap. In addition, I have noticed that a heavy use of dashed and dotted edges has had a significant (negative) impact on the performance, so I decided to disable them until I have found a suitable workaround for this. But now for the good news: I have rewritten large parts of the engine, a worthwhile effort, I believe, as you will hopefully notice the much smoother zooming function and the overall improved handling of the tool. I also added various other features, like support for a third attribute, but I suggest you just see for yourself. Different to former versions, this version is finally downwards compatible, which means you can still use the graphs you built with version 0.5 - I will try to make sure that any upcoming update will support all program versions since version 0.5 (included).
- The program is under construction and has not even reached beta state, meaning it still lacks main features and suffers from various bugs. In its current state it can be called prototypical at best. Please take this into account.
- Prior to starting the tool you may want to confirm that the latest Java version is installed on your PC or Mac. Click here to check. If needed, you can download the Java VM (at no cost) here for your PC. If you have a Mac, use the 'software update' feature from the menu. Here you can get a detailed explanation on how to do that.
- SysViz is a so called signed applet, meaning that each time you start the applet you will be asked whether you want to trust its certificate. Doing so will allow the program to function like any regular program you have installed on your system and grant it access to your harddrive, which is necessary for saving and loading files. If you do not want this (for whatsoever reason) you should refuse the certificate, but keep in mind that in this case you will not be able to save your graphs.
- The applet automatically adjusts to the resolution of your primary monitor.
- We use Google Analytics to count website visits and determine your rough location (city). Please read the disclaimer at the imprint (link at the bottom of this page). However, be assured that we do not monitor the usage of the applet itself.
- There is no manual available at the moment, but we hope to be able to supply some online help soon.
- Any other programs you are running, including additional browser tabs, will reduce the performance of the tool and may lead to heavy flickering, especially during the node rearrangement process after activating/deactiving the Radial View. Consequently, you should close all other programs/browser tabs before running the tool.
