Smile is a data visualization and automation software for Mac OS X. Its plotting interface makes easier to plot data by importing files, specifying intermediate computations and access display settings, all in the same interface. You can also work by writing scripts which perform the data processing tasks and which make the data visualization graphs. Such scripts can be integrated to a custom interface or to an automatized workflow. In order to increase the audience of Smile, Satimage-software offers to students free temporary SmileLab licenses (valid until June's last day). We also provide time-limited free trial licenses, valid 2 months, on a one per e-mail address basis.
