The Anatomy Of A Great Data Visualization Tool

Most charts include a legend to help readers comprehend the plotted data. The legend is a default in most visualization tools when rendering the graph for the first time. However, some visualization tools like FusionCharts allow users to customize the features of the legend itself. Thes customizable features include legend appearance, legend font, and so on.
