Understanding the Figure object
Plotly is a fully fledged data visualization system, which ships with more than 50 types of charts out of the box (for example, bar charts, scatter plots, and histograms). It supports 2D and 3D visualizations, ternary plots, maps, and more. The available options for customizing almost any aspect of your charts are very detailed and can be overwhelming.
