Vvizard is command line utility to convert text instructions to graphs. Its primary feature is the ability to automate graphs without an IDE, compiler, user interface or any other indirection.

How does it work? Launch the Terminal application (shell window), type "vvizard" and enter commands such as:


./vvizard
add chart_type line
add chart_subtype linear
add chart_format_type default
add title Vvizard Help Example Graph
add x_title My X Title
add y_title My Y Title
add data_1 1 2 2 4 3 6 4 2
add data_2 1 3 2 1.4 3 8.7 4 1.1
display

Those text instructions make a line graph with two curves (defined by the x y pair sequences of data_1 and data_2 respectively). For a semi-log line graph change the add chart_subtype linear instruction to add chart_subtype semilog. Type help for instructions. See The Vvidget Code Reference manual for a detailed explanation of the add parameters. To export, reformat and layout the graph for publication ready results using a comprehensive point-and-click tool see: Download Vvidget.

Because vvizard accepts input from the unix stdin stream you can use pipes and shell stdio redirects to automate graphs in many scripting languages.

The most important aspect of vvizard is its ability to make graphs directly, to give you the capability to export to a powerful point-and-click layout application when you want it and finally, to allow you to leverage your existing knowledge of the add parameters to write custom desktop applications with graphs in them via Xcode and other IDE toolsets.
