Sparkler is a browser based plotting tool. You can create multiple views of your data and can interact with points across the different facets. It is very useful for exploring outliers.
Sparkler does all the plotting work locally in your browser. Data is never sent to a remote server. This means you should only try working with data files that will comfortablly fit in your computer's availble memory.
Input data needs to be in a plain text format. Columns should be consistently delimited (either with tabs, commas, or spaces). The first row should contain a header indicating column names. The data must be "rectangular" meaning all rows must have the same number of columns.
Sparkler uses the following javascript libraries
