The present disclosure involves systems, software, and computer-implemented methods for preventing overplotting for data visualization. An example method includes identifying a request to generate a chart including a plotting area indicating a set of data points to be displayed in the plotting area of the generated chart; determining that the requested chart will be unsuitable for display; dividing the plotting area into a plurality of bins, each having a shape configured to tessellate the plotting area in response to determining that the requested chart will be unsuitable for display; assigning each data point to one of the plurality of bins based on a position of each data point within the plotting area of the requested chart; and generating a modified chart including the plotting area of the requested chart including the plurality of bins each configured to indicate a number of data points are assigned to the particular bin.
