The following three graphs are used to check that three assumptions are met in simple linear regression. The other assumption to check for a linear relationship can be done by looking at a scatter plot of the response variable and predictor variable. The data is about the behaviors and states of being for Americans in the Covid-19 pandemic. The observations are US states.

One can create awesome visualizations of animations in R using gganimate software. Gaze through these time series and scatter plots about Covid-19 data and temperature anomalies.

The flexdashboard feature in R enables creators to lay out some visualizations on a dashboard in a compact way. In this example, two time series graphs and one scatter plot of Covid-19 trends are presented in a dashboard.

The lab page provides code on how to use Plotly software in R for users to interact with graphs on Covid-19 trends and Star Wars characters' characteristics.
