"BioFabric is an open source software application for graph drawing.. It presents graphs as a node-link diagram, but unlike other graph drawing tools that depict the nodes using discrete symbols, it represents nodes using horizontal lines. Rationale Traditional node-link methods for visualizing networks deteriorate in terms of legibility when dealing with large networks, due to the proliferation of edge crossings amassing as what are disparagingly termed 'hairballs'. BioFabric is one of a number of alternative approaches designed explicitly to tackle this scalability issue, choosing to do so by depicting nodes as lines on the horizontal axis, one per row; edges as lines on the vertical axis, one per column, terminating at the two rows associated with the endpoint nodes. As such, nodes and edges are each provided their own dimension (as opposed to solely the edges with nodes being non-dimensional points). BioFabric exploits the additional degree of freedom thus produced to place ends of incident edges in groups. This placement can potentially carry semantic information, whereas in node-link graphics the placement is often arbitrarily generated within constraints for aesthetics, such as during force-directed graph drawing, and may result in apparently informative artifacts. Edges are drawn (vertically) in a darker shade than (horizontal) nodes, creating visual distinction. Additional edges increase the width of the graph. Both ends of a link are represented as a square to reinforce the above effect even at small scales. Directed graphs also incorporate arrowheads. Development The first version, 1.0.0, was released in July 2012. Development work on BioFabric is ongoing. An open source R implementation was released in 2013, RBioFabric, for use with the igraph package, and subsequently described on the project weblog. Features Input * Networks can be imported using SIF files as input. Related Work Blakley et al. have described how the technique used by BioFabric, which they refer to as a cartographic representation, can be used to compare the networks A and B by juxtaposing the edges in (A ∖ B), (A ∩ B), and (B ∖ A), a technique that is evocative of a Venn Diagram. Rossi and Magnani. have developed ranked sociograms, which is a BioFabric-like presentation where the node ordering is based upon a ranking metric. This approach attaches semantic meaning to the length of the edge lines, and can be used to visualize the assortativity or dissortativity of a network.

"Yassine Brahim (; born 20 February 1966 in Mahdia, Tunisia) is a Tunisian engineer, manager and politician. Leader of the secular liberal Afek Tounes party, he was appointed Minister of Development, Investment and International Cooperation in February 2015. Early life and education Born 1966 in Mahdia, Brahim was raised in Bizerte by Tunisian Air Force officer Mahfoudh Brahim and his mother, a teacher and daughter of revolutionary Abdelaziz Mastouri. When he was ten years old, they moved to Carthage where Brahim visited secondary school. With a stipend of the Tunisian government, he left Tunisia in 1983 for a preparatory course in Toulouse, France. In 1989 he received his diploma in Engineering at École Centrale Paris. Professional career Brahim subsequently worked for Cap Gemini. A job with French bank Société Générale led him back to Tunisia, where in 2000 he founded his own information services company 2ic which in 2004 he sold to French company Teamlog. He joined financial software company Ubitrade and when his company was sold to GL Trade in 2006, he moved to London being appointed general director of the new company, which he led into the following acquisition by U.S. based SunGard. Political career In 2010 he turned back to Tunisia, just before the Tunisian Revolution would lead to his appointment as Minister of Transport and Equipment in the short-lived second Ghannouchi cabinet and the subsequent Essebsi cabinet. He resigned on 17 June 2011 to become general secretary of the newly founded Afek Tounes party which he led into a merger with Ahmed Najib Chebbi's Progressive Democratic Party, the Republican Party Al Joumhouri. On 28 August 2013, Brahim however announced the cession from the Republican Party reestablishing Afek Tounes as an independent liberal party. In the 2014 legislative election, Afek Tounes won 8 seats and Brahim himself was elected to represent the Mahdia constituency at the Assembly of the Representatives of the People. In February 2015, Afek Tounes agreed in a unity government with Nidaa Tounes and rival UPL. In prime minister Habib Essid's cabinet, he became Minister of Development, Investment and International Cooperation.
