data vizualization libraries
Since I started my quest a few years ago searching for the ultimate knowledge management tool, I’ve discovered a number of interesting applications that help people efficiently organize information. There certainly is no shortage of solutions for this problem domain. Many tools exist that offer the ability to discover, save, organize, search, and retrieve information. However, I’ve noticed a trend in recent years, and some newer applications are focusing more on the visual representation and relationship of knowledge. I believe this is in part due to the wider adoption of mind mapping (and concept mapping), and leveraging concepts and advances in the semantic web community.

Graph Drawing is concerned with the geometric representation of graphs and networks and is motivated by those applications where it is crucial to visualize structural information as graphs. Since graph drawing methods form the algorithmic core of network visualization, bridging the gap between theoretical advances and implemented solutions is an important aspect. This site is a collection of resources mostly related to the annual International Symposium on Graph Drawing, but we anticipate the inclusion of, e.g., an overview of software tools in the future. graphdrawing.org
