What should an ArcGIS user do before displaying a point file as graduated symbols, when multiple points share the same coordinates?

Before displaying a point file as graduated symbols in ArcGIS, especially when multiple points share the same coordinates, it is crucial to collect events. This process involves aggregating or summarizing the duplicate points into a single representation. By doing so, the visualization can effectively convey the magnitude or significance of the data at that specific location rather than simply overlaying multiple symbols on top of one another, which could lead to confusion and misinterpretation.

When using graduated symbols, the aim is to represent quantitative data, and this representation is most meaningful when each symbol accurately reflects the underlying data at unique locations. Collecting events allows the user to handle multiple occurrences in a more logical manner, enabling the display of average values, sums, or counts rather than a dense cluster of symbols that would be indistinguishable.

Other methods, while useful for different analytical purposes, do not address the visual and representation challenge posed by overlapping data points in the context of graduated symbols on a map. For instance, generating a spatial weights matrix is more related to spatial analysis and understanding relationships between features, while cluster and outlier analysis and hot spot analysis deal with identifying patterns in the data rather than how to visualize overlapping data points effectively. Collecting events directly addresses the need to manage and summarize
