![]() ![]() Allows more than one connection between two bioentities Supports weighted graphs Has its own test files format that is not compatible with other viz. 2D visualization of small networks with up to a few hundred nodes and edges. Java application available also in a form of an applet This is an open source product Visualization is based on the Fruchterman-Reingold algorithm. ![]() Criteria for the assessment of visualization tools include: - power - efficiency and quality of network visualizations produced - the compatibility with other tools and data sources - the analytical functionalities offered, - limitations in terms of data quantity - broad applicability - user-friendliness The survey covers tools invented mainly over the past five years. In such cases visualization tools based on multi-edged networks offer the possibility to link two vertices by multiple edges, every edge having a different meaning and information value.ĥ Solution The goal of all presented tools is to find patterns and structures that remain hidden in the raw unstructured datasets. Graphs, as specified by graph theory, represent biological interactions in the form of extensive networks consisting of vertices, denoting nodes of individual bio-entities, and edges, describing connections between vertices.Ĥ Solution Biological systems are complex and interwoven and in most cases single-line connections are insufficient to capture the whole range of information contained in a network, because components are often linked by more than one type of relationship. Growing quantities of data obtained by the newly developed technologies Exponentially growing bio-medical scientific literature Growing complexity of data Need to integrate heterogeneous types of dataģ Solution An interactive visual representation of information together with data analysis techniques is often the method of choice to simplify the interpretation of data.
