choropleth map -- 3

I need to learn about choropleth maps in D3.js, and then use the data sets found on the CDC websites to create my own site. The CDC website allows users to see Covid cases with different views, in different time periods, and under different metrics. You don't need to replicate all functions provided by the CDC website. The website should support the following functions:

Three views of Cases, Deaths, and Vaccination Progress ( % full vaccinated). Time period and metric functions are not required;
View switch through HTML components (e.g., radio buttons, or a drop-down menu);
Tooltip function that allows users to get basic information by hovering the cursor over a state;
