Advanced Graphs and Charts Collection for PHP provides a very easy way to embed dynamically-generated graphs and charts into PHP applications and HTML Web pages. The Graphing components provide various solutions for the incorporation of graphs and charts into Web/intranet pages and applications. Versatile components provide the ability for Web authors and developers to quickly build and publish dynamic and interactive graphs and charts.
yEd is a powerful diagram editor which can be used to quickly create diagrams manually or import external data for analysis and auto-magically arrange even large data sets by just pressing a button. You can use yEd to quickly create flow charts, BPMN and UML diagrams, organization charts, mind maps, Entity Relationship diagrams, and many other kinds of diagrams, graphs, and networks. Choose from a wide range of highly sophisticated layout algorithms to automatically arrange diagrams in no time. An intuitive and visually appealing user interface makes creating diagrams fun. Once a diagram has been created, it's easy to save, print, or export it to popular formats like PDF, SWF, EMF, SVG, JPEG, GIF, PNG, or HTML image maps.
PHPStateMapper is a PHP library for drawing a map with areas shaded by varying degrees of intensity based on data given as a simple list. It exports a PNG image in a configurable size and color. It is appropriate for generating images for use in reporting and analytics. Data can be loaded programmatically or from a comma separated values (CSV) source file.
Self-Adjusting Top Tree Implementation maintains a forest that changes over time through edge insertions and deletions. This implementation focuses on the simplified Top Tree interface, which allows you to solve a number of interesting graph problems like finding common ancestors, the heaviest edge, maintaining the diameter, center, or median and other (mostly network flow) problems. Using Top Tree interfaces, all outline problems can be solved in a clean declarative way. This implementation uses adapting ST-trees as the underlying data structure, achieving O(log n) time per expose(v,w) operation. There is also a demo that shows an easy way to integrate the toptree library and the host application.
