Which of the following types of data visualization is supported by ArcGIS Online?

ArcGIS Online excels in geographical data visualizations, which utilize maps and spatial analysis to represent data in a way that highlights relationships, patterns, and trends in relation to geographic locations. This platform leverages the power of GIS (Geographic Information Systems) to transform raw data into meaningful visuals that can be dynamically analyzed and shared.

Geographical data visualizations in ArcGIS Online can include various formats such as thematic maps, 3D scenes, and interactive web maps that allow users to explore data by zooming, panning, and filtering based on attributes or geographical features. The emphasis is on spatial context, making it a powerful tool for understanding the implications of data in real-world scenarios, facilitating better decision-making and communication.

In contrast, the other options listed do not represent the primary functions supported by ArcGIS Online. For instance, interactive video content and real-time sound data visualizations are not fundamental features of the platform. Additionally, while static infographics can be created, they do not leverage the interactive, dynamic capabilities that geographical data visualizations provide within ArcGIS Online. This distinction underscores the focus of ArcGIS on spatial data and geographical analysis.
