generate_district_map

Generates regional distribution maps, which are usually used to show the administrative divisions and coverage of a dataset. It is not suitable for showing the distribution of specific locations, such as urban administrative divisions, GDP distribution maps of provinces and cities across the country, etc. This tool is limited to generating data maps within China.

Parameters:

• title (string, required): The map title should not exceed 16 characters. The content should be consistent with the information the map wants to convey and should be accurate, rich, creative, and attractive.
• data (object, required): Administrative division data, lower-level administrative divisions are optional. There are usually two scenarios: one is to simply display the regional composition, only fillColor needs to be configured, and all administrative divisions are consistent, representing that all blocks are connected as one; the other is the regional data distribution scenario, first determine the dataType, dataValueUnit and dataLabel configurations, dataValue should be a meaningful value and consistent with the meaning of dataType, and then determine the style configuration. The fillColor configuration represents the default fill color for areas without data. Lower-level administrative divisions do not need fillColor configuration, and their fill colors are determined by the colors configuration (If dataType is "number", only one base color (warm color) is needed in the list to calculate the continuous data mapping color band; if dataType is "enum", the number of color values in the list is equal to the number of enumeration values (contrast colors)).
