Create a Bar Chart From a DataFrame with Plotly and Flask
Python has a number of powerful open-source libraries that make it an excellent language for Data Analysis and Web Development. One such library is Plotly, which makes it easy to create compelling data visualizations using web technologies. By combining Plotly with Flask, it is possible to create dynamic web pages that update automatically based on user interactions with the data. This article shows you how to use Plotly with Flask to generate a set of plots from the data stored in Pandas Dataframe.
pip install pandas pip install plotly
Import the necessary modules. Have a dataset and design a home page route (Use default datasets available online or create our own). Dataset conversion to a Pandas Dataframe Now, we’ll use the Dataframe, Plotly, and px.bar to construct a bar chart (). Then, turn the figure into a JSON Object and send it using a render_template to the HTML page.
Run the command in the terminal.
