A data visualization 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 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 ith 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 and the length of a column bar represents a quantity of behaviors in a time period corresponding to the column bar.
