DATA VISUALIZATION METHOD AND DEVICE

摘要

Embodiments of the present invention provide a data visualization method and apparatus, where the method includes: acquiring a spatiotemporal behavior data set generated by network users; determining, according to a time point at which or a time period in which each piece of spatiotemporal behavior data is generated, an amount of spatiotemporal behavior data that is in the spatiotemporal behavior data set and that is generated at a time point or in a time period falling within each time period in N time periods; and presenting a column bar corresponding to an i th time period in the N time periods, where the column bar is in a radial direction of a first circle representing a full time domain and intersects the first circle. In the embodiments of the present invention, a first circle represents a full time domain, and a length of a column bar represents a behavior quantity in a time period corresponding to the column bar. By combining the first circle and the column bar, distribution of the behavior quantity in a full time domain can be visually presented, thereby implementing visualization of spatiotemporal behavior data from a perspective of a time domain.
