With the course of time accumulated business data, the data in terms of the number of production space or from the dimension hierarchies are increasingly complex. The face of large amounts of data, management often feel powerless and frustrated: either a large number of enterprise production data can not be used effectively, can not provide a basis for decision making; obscure or complicated data presentation mode, not effective rapid screening information. How huge amounts of data through extraction, processing, refining, show by visual way out, to change the traditional text descriptions to identify patterns, policy makers more efficient to obtain important information and understanding of the important details, it relates to the development and direction of major decisions of enterprises judgments.
Data visualization can provide an ideal solution to the above problems. Data visualization refers to the graphical histograms, pie charts, line charts, and display data, more efficient decision-makers important information and level of detail of enterprises. Numerous studies have shown that human speed access to information through the graphics much faster than the speed of access to information by reading the text, so by visual way to help users to change the traditional pattern recognition data.
I think a good data visualization tool should have the following aspects:
(1) to support access to multiple data sources such as Excel files, CSV, relational databases, large data storage platform, search engine ...
(2) modeling a variety of data, such as drag modeling, SQL modeling, process modeling ... stored 
drag modeling and SQL modeling formula 
(3) rich visual display components, such as a bar graph, line graphs, pie charts, maps GIS, Sankey diagram form, FIG sun, parallel coordinates, calendar FIG heat ... 
(4) analysis of a variety of interactive operations, such as data linkage, drill, drilling, filtering parameters, filter assembly ... 
(5) flexible own layout mode 
(6) to facilitate the sharing and viewing
