To immediately transmit encoded data as understandable information by three-dimensionally displaying information, and separating arcs so as not to be visually crossed in a display by the interactive control of a visual point by a user.

A picture indicating an internet traffic between nations is formed, the nodes are defined s the nations, and the nations are connected through the traffic by a link so that time sequential data for a global network can be displayed. The formed data are three-dimensionally displayed on the screen of a display 102, and the earth is irradiated with a light arranged so that the angle of the sun against the frame of the data can be reflected. Node statistic is indicated by a glyph arranged on the earth, and the characteristic of the glyph is encoding the various node statistic. The link is indicated by arcs connecting the node glyph, and the characteristic of the arc is encoding the various link statistic. A user can interpret the encoded data by interacting with the display 102 by using pointing devices 104 and 106.
