In the embodiment of the application, the underlying canvas can be understood as a drawable area with a drawing function in the digital map.
In practical applications, the electronic device may create a Canvas (Canvas) element with which to generate a digital map, such as an underlying Canvas over a GIS map. The Canvas element is an element added by HyperText Markup Language (HTML) and is used for generating a graphic container (Canvas) so as to perform drawing and rendering of graphics in the Canvas.

Specifically, when the scalable vector grid map is arbitrarily scaled, the definition of the grid graph is not affected, so that the drawn grid graph can be adapted to the first area requirement with different area attributes in the digital map.
In the embodiment of the application, after acquiring the grid configuration parameter and the first grid set, the electronic device dynamically generates a Scalable Vector Graphics (SVG) graph based on the grid configuration parameter and the first grid set, performs format conversion on the generated SVG grid graph by using base64 coding, acquires a coded graph, and transmits the coded graph in a binary code stream form. Therefore, the pictures do not need to be stored locally in an address form or loaded in the address form, the transmission rate of the pictures is improved, and the user experience degree is greatly improved.

It should be noted that the target configuration parameters corresponding to grids with different grid attribute information are also different.
Step S2, generating a scalable vector grid map based on each grid subset and each target configuration parameter.
In the embodiment of the application, the electronic device dynamically generates the scalable vector grid pattern corresponding to each grid set and each target configuration parameter based on each grid set and each target configuration parameter.
In practical applications, as shown with reference to fig. 4, the first grid set includes grids in which at least one vertex coordinate of the grid is located in the second region surrounded by the black border line 41; the method comprises the steps that the electronic equipment obtains grids with data information in a first grid set in real time, such as telephone traffic data, compares the telephone traffic data information obtained in real time with a preset threshold value of the telephone traffic data corresponding to the electronic equipment to obtain a first grid subset corresponding to the telephone traffic data higher than the telephone traffic preset threshold value and a second grid subset corresponding to the telephone traffic data lower than the telephone traffic preset threshold value, wherein the grids in the first grid subset are grids pointed by a black filled rectangle 42, the grids in the second grid subset are grids pointed by an oblique line filled rectangle 43, and first target configuration parameters corresponding to the first grid subset, such as target configuration parameters filled in the grids and shaped like multiple oblique lines, are obtained; and acquiring a second target configuration parameter corresponding to the second grid subset, for example, a target configuration parameter filled in the grid and having a single oblique line shape. A scalable vector grid map is generated based on the first grid subset, the second grid subset, the first target configuration parameter, and the second target configuration parameter.
In other embodiments of the present application, after obtaining each grid subset, the electronic device may further obtain grid attribute information, that is, included data information and area attribute information, of a single grid included in each grid set. By scaling a single grid, the division manner of the grid and the display manner of the data information in the areas of different levels of the grid can be obtained, as shown in fig. 5, fig. 5 shows the display manner of the data information in the area of a smaller level of the grid based on the division manner of the grid corresponding to the area attribute information. Illustratively, each building is represented in a cubic display, and names of buildings corresponding to the separated cubes are indicated in fig. 5, such as office building 1 seats.
