What visualization is best for displaying data on customer complaints related to bus routes?

A Line Layer Map is particularly effective for visualizing customer complaints related to bus routes because it allows for the geographic representation of data points tied to specific locations. This visualization can show the routes on a map, where each complaint can be plotted based on its geographic coordinates. By using this type of map, stakeholders can easily identify hotspots of complaints, analyze the geographical distribution of issues, and make informed decisions about where to allocate resources or take action to improve customer satisfaction.

In contrast, a Bar Chart would summarize complaints in a categorical manner, which may not convey the spatial context essential for analyzing bus routes. A Heat Map could show density of complaints, but it may not provide specific details about the routes themselves. A Scatter Plot typically illustrates relationships between two variables and wouldn’t facilitate the geographic visualization necessary for this specific context.
