• Fulfill the below user stories and get all of the tests to pass. Give it your own personal style.

• You can use HTML, JavaScript, CSS, and the D3 svg-based visualization library. The tests require axes to be generated using the D3 axis property, which automatically generates ticks along the axis. These ticks are required for passing the D3 tests because their positions are used to determine alignment of graphed elements. You will find information about generating axes at https://github.com/d3/d3/blob/master/API.md#axes-d3-axis. Required (non-virtual) DOM elements are queried on the moment of each test. If you use a frontend framework (like Vue for example), the test results may be inaccurate for dynamic content. We hope to accommodate them eventually, but these frameworks are not currently supported for D3 projects.

• User Story #1: My tree map should have a title with a corresponding id="title".

• User Story #2: My tree map should have a description with a corresponding id="description".

• User Story #3: My tree map should have rect elements with a corresponding class="tile" that represent the data.

• User Story #4: There should be at least 2 different fill colors used for the tiles.

• User Story #5: Each tile should have the properties data-name, data-category, and data-value containing their corresponding name, category, and value.

• User Story #6: The area of each tile should correspond to the data-value amount: tiles with a larger data-value should have a bigger area.

• User Story #7: My tree map should have a legend with corresponding id="legend".

• User Story #8: My legend should have rect elements with a corresponding class="legend-item".

• User Story #9: The rect elements in the legend should use at least 2 different fill colors.

• User Story #10: I can mouse over an area and see a tooltip with a corresponding id="tooltip" which displays more information about the area.

• User Story #11: My tooltip should have a data-value property that corresponds to the data-value of the active area.

• For this project you can use any of the following datasets:

  • Kickstarter Pledges: https://cdn.rawgit.com/freeCodeCamp/testable-projects-fcc/a80ce8f9/src/data/tree_map/kickstarter-funding-data.json
  • Movie Sales: https://cdn.rawgit.com/freeCodeCamp/testable-projects-fcc/a80ce8f9/src/data/tree_map/movie-data.json
  • Video Game Sales: https://cdn.rawgit.com/freeCodeCamp/testable-projects-fcc/a80ce8f9/src/data/tree_map/video-game-sales-data.json

• You can build your project by forking this CodePen pen. Or you can use this CDN link to run the tests in any environment you like: https://cdn.freecodecamp.org/testable-projects-fcc/v1/bundle.js

• Once you're done, submit the URL to your working project with all its tests passing.

• This responsive visual graphic map is built on top of D3 version 5 library. To achieve responisve map, SVG view box is being used.

  viewBox="minx miny width height"
  
  viewBox="0 0 200 150"
  
  

• D3v5 substituted asynchronous callbacks with promises. Therefore, fetching external data is different from previous version. In previous the data used to be fetched in this order

  var data = d3.json(‘data.json’, function(data){
      //then do something with data
      console.log(data)
  });
  

• However, the promises in later version is slightly different from previous one. If, you have no idea what promises is all about? Kindly, do some research on Javascript’s promises and fetch(url). The syntax in D3v5 looks

  var data = d3.json(‘data.json’).then(function(data){
      return (data);
  }).catch(function(err){
      console.log(err)
  });
  

• Treemap is zoomable. Point to the selected area of the map and left click to initialize zoom in behaviour.
• To Zoom out click on the orange bar in the header.
• Information can be viewed by pointing on any area of map.
• For test to pass, test need to run in child page that is after zooming in the intial page.
• Dropdown menu on top right contain list of different product(s) details.
