Setting up

We recommend you use node version 20. Use nvm if you need to switch versions.

• Use npm install to install dependencies
• Use npm run dev to compile & run the application. It will run on localhost:5173

Task

• The goal is to get familiar with JavaScript, TypeScript, React, and Material-UI
• You will be working in the src/ directory. Ignore public/, node_modules/, .gitignore, package.json, and package-lock.json, and all other files outside src/.
• Step 0: Get your dev environment running. Make sure that when you run npm run dev you see the landing page with text.
• Step 1: Create a list of all states, and display it on the page. Source file: src/library/state_data.json
• Step 2: When a state from the list is clicked, display a list of all counties in that state. County source file src/library/county_data.json
  • Notice that there is a field called GISJOIN associated with each entry in both of these files. You'll want to read the contents of these files into a data structure which you can search. The first 4 characters is a county's GISJOIN match it's associated state's GISJOIN. For example, Calhoun county's GISJOIN is "G0100150". We know this is in Alabama because Alabama's GISJOIN is "G010".
  • The selected state can be 'cleared', which causes the County list to disappear.
• Step 3: Allow the user to search for counties by name. This involves a TextField that the user can type into, which filters the displayed counties.
  • This list is conditionally rendered. When no state is selected or when the selected state in cleared, this list does not show up.
• Step 4: When a county is clicked, the map zooms to that county.
  • Use the sendRequest() function
• Step 5: Make 3 charts
  • Pie chart for counties that begin with vowels vs consonants
  • Line chart of number of letters per county
    • x-axis: county names
    • y-axis: number of letters
  • Histograph (bar chart) of number of counties with which number of letters
    • x-axis: numbers of letters in county names
    • y-axis: number of counties with the corresponing number of letters
• Ask Matt any clarifying questions! Reach out on MS Teams, or email [email protected]
• NOTE: Use good software engineering practices (SRP, generalized components, clean code)
