Read more about caching in Streamlit docs. Then every time you rerun your app, the data will stay memoized! This way you can avoid downloading the dataset again and again. Adding the decorator will make the function get_data() run once. Next, add the pd.read_csv() call within a new function get_data() so that it gets properly cached. But remember, this data source could be streaming from an API, a JSON or an XML object, or even a CSV that gets updated at regular intervals. You can read your input data in a CSV by using pd.read_csv(). Import streamlit as st # 🎈 data web app development Import plotly.express as px # interactive charts Import pandas as pd # read csv, df manipulation Go ahead and import all the required libraries: import time # to simulate a real time data, time loop In this case, you’ll use a Comma Separated Values (CSV) file. You’ll use pandas to read the input data source. Use NumPy to generate data and make it live (looped) with the Time library (unless you already have a live data feed). Because you don’t have a data source, you’ll need to simulate a live data feed. As you might’ve guessed, you’ll be using Streamlit for building the web app/dashboard. Here are the libraries that you’ll need for this dashboard:
