The invention discloses a method for realizing visual interactive navigation of a knowledge graph, which comprises the following steps of: drawing a synchronous dynamic navigation graph in a preset navigator on the premise that a knowledge graph main graph drawing method is compiled, adding a bush layer to the navigator to display the position and size of the current viewport of the main graph relative to the node area of the whole graph, mapping the current visual area of the main image to a navigator bush layer to realize corresponding size and position change of the navigator bush when themain image is moved, zoomed and dragged by a node, calculating the position of the main graph node area relative to the viewport according to the position of the bus in the navigator, correcting the navigator according to the layout form of the main map, and switching according to the layout form of the main map, and correcting the content of the navigator. According to the method, the size and position relation between t
