What is Plotly Express and its methods?

Plotly Express is a high-level data visualization library in Python that provides a simplified syntax for creating interactive visualizations. It is built on top of the Plotly graphing library, which provides low-level control over graphs and figures.

Plotly Express functions

Plotly Express provides a simple and intuitive syntax for creating various visualizations, from simple scatter plots to complex 3D surface plots and maps. It also includes support for creating animations and subplots and providing built-in color scales and easy customization options. Here’s a list of some of the most commonly used functions of Plotly Express:

• scatter: This creates a scatter plot from the x and y variables.

• line: This creates a line plot from the x and y variables.

• bar: This creates a bar plot from the x and y variables.

• histogram: This creates a histogram from a single variable.

• box: This creates a box plot from the x and y variables.

• violin: This creates a violin plot from the x and y variables.

• density_contour: This creates a density contour plot from the x and y variables.

• density_heatmap: This creates a density heatmap plot from the x and y variables.

• scatter_3d: This creates a 3D scatter plot from x, y, and z variables.

• line_3d: This creates a 3D line plot from x, y, and z variables.

• scatter_matrix: This creates a matrix of scatter plots from a DataFrame.

• parallel_coordinates: This creates a parallel coordinates plot from a DataFrame.

• scatter_mapbox: This creates a scatter plot on a Mapbox map.

• choropleth: This creates a choropleth map from a GeoJSON file or a pandas DataFrame.
