What type of layer allows for visualization of statistical data in a web map format?

1. Raster layer

2. Feature layer

3. Image layer

4. 3D object layer

The correct answer is: Feature layer

The feature layer is the correct choice because it is specifically designed to represent and visualize vector data in a web map format, which often includes statistical attributes. Feature layers allow users to display point, line, and polygon data while also enabling interactivity, such as querying and filtering based on attribute data. This is particularly useful for visualizing statistical data since these layers can represent changes, distributions, and trends over geographic areas. Feature layers not only allow for the visualization of data but also enable the application of symbology to represent various data categories, as well as facilitate labeling based on attributes. This makes them an essential component for analyzing and interpreting statistical information in a geographical context. In contrast, other layer types, like raster or image layers, are generally used for different purposes, such as displaying image files or pixel-based data without the same level of interactivity or attribute representation.
