Visual data analysis method and system

The invention discloses a visual data analysis method and system, and the method comprises the steps: obtaining the geographic position data of a business district, and carrying out the three-dimensional modeling of the geographic position data of the business district, and forming a first business district map; constructing grids in the first business district map, wherein an AIoT device is configured in each grid to detect and obtain a multi-dimensional influence factor data set; performing weighted regression statistics on different influence factor values in each grid by adopting a geographic weighted regression algorithm to obtain different influence factor values of each grid; and setting a grid fusion index of a business circle block type division criterion, and according to the grid fusion index, fusing the adjacent grids of which the influence factor values meet the grid fusion index in the grids to obtain a spatial distribution diagram corresponding to the business circle block type division. 本发明公开了
