Abstract: A system and method of facilitating data visualization provides for plotting a plurality of independent variable values along an axis of a web-based chart. The plurality of independent variable values corresponds to a plurality of data points. Notification of a user selection of an area of the chart is received and a dependent variable of a particular data point is animated as a speedometer reading if the selected area corresponds to an independent variable value of the particular data point.

Abstract: A system and method of facilitating data visualization provides for receiving a user response to a data entry interface via a network, where the user response defines a first data set and a second data set. Data points in the first and second data sets include dependent variable values. A first chart is generated based on the first data set and a second chart is generated based on the second data set. An appearance of the second chart is modified if a user-selected area of the first chart corresponds to a first data point in the first data set and the first data point has a predetermined relationship with a second data point in the second data set.
