Heat maps are an effective method to visualize inventory turnover rates across multiple product categories because they allow for the comparison of data through color coding. Each color represents different levels of turnover, thus providing an immediate visual cue regarding which categories are performing well or underperforming. This method is particularly useful for displaying large amounts of data at a glance, making it easier to identify trends and patterns that may not be as easily discernible with other types of charts.

Line charts might typically be used to display trends over time for a single category or a small number of categories, but they do not provide the comparative visual power needed for multiple categories. Bar graphs can also present comparison data but may lack the immediate visual impact and ease of interpretation that heat maps offer, especially with larger datasets. Pareto charts are useful for identifying the most significant factors in a set of data but do not provide a comprehensive view of turnover rates across several categories simultaneously. Therefore, heat maps stand out as the most suitable choice for visualizing inventory turnover rates.
