PROBLEM TO BE SOLVED: To solve the problem in a conventional search tree drawing method, that an area of a figure indicative of each node is too small to simultaneously display, in the node, a plurality of attributes included in a data set belonging to subordinate nodes of the node though a tree structure of a search tree can be drawn.SOLUTION: In a search tree drawing device, a search tree drawing method and a program, a figure indicative of a node is represented by a cone, and cones indicative of respective nodes are arranged so that apexes of cones indicative of child nodes are in contact with an outer periphery of a bottom of a cone indicative of a parent node, whereby a tree structure can be drawn without using lines showing relations between the nodes and the cone indicative of each node can be drawn large. |
