Many modern visualization frameworks support users to declaratively define charts by their logical specifications. But these systems do not support the declarative definition of nonstandard charts. To solve this problem, we proposed a new visualization framework. Users can use it to declaratively define both standard charts and nonstandard charts from their logical specifications. Such a specification is described by one or more pairs of Data View Schemata (DVSs) and Chart View Schemata (CVSs). Each DVS is used for retrieving and processing data. Each CVS is used for defining the appearance of each chart component and defining how to use graphical objects to represent data. Because the rapid development of Semantic Web, we further extend our visualization framework to support users to exploratorily search Semantic Web through a node in the DVS. By manipulating the DVS, users can define a view of Semantic Web Resources. Users can also further manipulate this generated DVS to integrate the data from local databases and those from Semantic Web, and then visualize the integrated data with a nonstandard chart.
