Visual distributed data framework for analysis and visualization of datasets

摘要

A system represents data as visual distributed data frames (VDDFs) that comprise a dataset, metadata describing the data, and metadata describing visualization of the dataset. A VDDF may be extracted from charts displayed in markup language documents. A VDDF may be generated from different data sources including big data analysis systems. A VDDF workspace allows interaction with multiple VDDF objects extracted from multiple data sources and stored locally within the storage of the device. The VDDF workspace allows the user to interact with the VDDF objects, for example, by inspecting the metadata, modifying the data, adding new columns, changing the visualization, joining data from multiple charts, and sharing the VDDF objects with other documents. The processing of data of a VDDF is performed locally within a computing device, for example, in a client device.
