PHPLOT is a PHP graphics class for creating charts and plots. It works with PHP5 (but older versions can use PHP4). PHPlot uses the PHP GD extension to produce PNG, GIF, or JPEG images. TrueType fonts (TTF) are optional, or built-in GD fonts can be used. The available plot types are: area, bars, line/points, lines, pie, points, squared, stacked-bars, and thin bar-line. Labels, tick marks, plot legend, X/Y axes, and more are all configurable. Images can be imported as a background, multiple graphs can be drawn on one image, and images can be saved to disk or returned to a browser.
pgintcl is a pure Tcl interface to the PostgreSQL database system. It provides an alternative to pgtcl and pgtcl-ng but does not require a compiled Tcl extension (libpgtcl) or PostgreSQL client library (libpq). This allows developers to create Tcl utilities and applications that are platform neutral. Trade-offs are slower performance and PostgreSQL protocol version dependency.
