DataMelt 1.7 DataMelt (DMelt), is a platform for numeric computation, data analysis, statistics and data visualization. DMelt can be used for analysis of large data volumes, data mining, statistical analyses and math computations. DMelt creates high-quality vector-graphics images (SVG, EPS, etc.) that can be included in LaTeX and other text-processing systems. As a computational platform, one can use a number of languages, such as Python (Jython), Java, Groovy, Ruby (JRuby), BeanShell and Octave.
