Aggregation
    Combine data observations into summary statistics. Aggregations are used by
    Mosaic to generate Shader plots.

Blaze
    Is a Python library and an ecosystem of related projects sponsored
    primarily by Continuum Analytics, and a DARPA XDATA grant. Blaze provides
    Python users high-level access to efficient computation on inconveniently
    large data. Mosaic uses Blaze for interactive exploration of datasets.

Coerce
    Change the data type into another. An example is converting an integer into
    a floating point value.

Datashape
    Schema information used in Mosaic. It shows metadata information about the
    current dataset: the number of rows, the column names and types.

Split-Apply-Combine
    Grouping operations that break a table into pieces and perform some
    reduction on each piece.

URI
    Uniform Resource Identifier. Is a string of characters to identify the data
    source and the backend to use in Mosaic.
