Create Default-Style Custom Thematic Map

Feature Description

Click the "Thematic Map" tab's "Custom Thematic Map" button to create a custom thematic map based on the current vector layer.

Select a vector layer in the Layer Manager for creating the custom thematic map.
Right-click and choose "Create Thematic Map ..." from the context menu. In the dialog box, click "Custom Thematic Map", then select a thematic map template from the right panel to create a default-style custom thematic map.
Configure style control fields in the "Custom Thematic Map" window to generate the map. It will automatically add to the current map window as a thematic layer, and a corresponding thematic layer will appear in the Layer Manager.

The Custom Thematic Map configuration window displays current thematic map settings: fill schemes, line patterns, symbol schemes, etc. Users can modify these style settings to refine the template-generated map for better visualization.
After closing the "Custom Thematic Map" window, double-click the layer in the Layer Manager or right-click and select "Modify Thematic Map" to reopen the configuration window for adjustments.
