It is Canada’s largest fast-food restaurant chain with 4,846 stores in 14 countries, by December 31, 2018, according to Wikipedia. In this article, we will use a dataset of Tim Hortons Locations from Kaggle to show how to create interactive visualizations of latitude and longitude on maps with Plotly and Python. From these plots, we can easily answer a question:

Detecting outliers is a crucial step in EDA (exploratory data analysis), and sometimes itself is the goal of machine learning projects. There are outliers in almost any dataset in the world. Catch and understand outliers can inspire business insights, and lead to further research or possible solutions.

How to apply data visualization to identify outliers? How to plot with Plotly or Seaborn by writing a few lines of Python code? This article will use a Covid-19 dataset as an example to demonstrate how to catch anomalies from the 50 states of America. The answers we can get from outliers include:
