The application relates to a map, namely, a
visual query system, which comprises the following function modules: a visual map screening function module, which is used for screening graph data on a map page; an edge query function module, which is used for querying according to the type of an edge; a path and snapshot saving function module, which is used for saving a current path and results in an operation path; a name display function module, which is used for setting the display type of a name; a
statistical function module, which is used for statistically describing graph data; a page turning function module, which is used for turning the current graph
data page; a permission management function module, which is used for managing permissions; an early warning function module, which is used for realizing the early warning function of graph data
abnormality according to the hop check-off method; a
label real-time dynamic function module, which is used for realizing the real-time dynamic change of a
label; and a map
generation time prediction function module, which is used for providing the progress
estimation of map generation. Compared with the prior art, the application has the advantages of optimizing
visual experience, improving abnormal early warning capability and the like.
