Attempting to visualize large, dense datasets can feel daunting. Large datasets typically have many overlapping features, which makes it difficult and sometimes impossible to view spatial patterns in raw data. This session demonstrates several ways you can visualize large datasets effectively, giving developers more confidence in their ability to make sense of large amounts of data. You will learn client-side techniques to visualize density, clusters, and hot spots, as well as server-side data preprocessing and aggregation workflows.
