力导向图力导向图(Force-Directed Graph),是绘图的一种算法。在二维或三维空间里配置节点,节点之间用线连接,称为连线。各连线的长度几乎相等,且尽可能不相交。节点和连线都被施加了力的作用,力是根据节点和连线的相对位置计算的。根据力的作用,来计算节点和连线的运动轨迹,并不断降低它们的能量,最终达到一种能量很...
PylibsNet can be visualized using graph and matrix, displaying node information (libInfo). The PylibsTree (depends on pipdeptree) can be displayed using six tree layout. PyNet and PyClass data can be visualized using a force-directed graph and matrix. PyTree can be visualized using six ...

ForceAtlas2 is a very fast layout algorithm for force-directed graphs. It's used to spatialize aweighted undirectedgraph in 2D (Edge weight defines the strength of the connection). The implementation is based on thispaperand the correspondinggephi-java-code. Its really quick compared to the fr...

However, in the presence of multiple inheritance (which makes the inheritance graph a general Directed Acyclic Graph rather than specifically a tree), this simple approach might lead to some ancestor class being visited twice. In such cases, the resolution order leaves in the lookup sequence only...

An attempt to place a bead (step) in the random walk is rejected, if a maximum force on the placed bead is exceeded. The self-excluding random walk is by default performed along a breadth-first traversal of the molecular graph. This means nodes (i.e., residues) that are close to ...
