To get the main D3.js JavaScript file go to the D3.js Website. After the first paragraph on the page, you will see a section with links to the latest version. Download the latest version d3.v5.min.js. Save this file in the d3js_projects folder.
The file d3.v5.min.js is saved in the same folder as the HTML file so that it can be referenced it easily. We reference the JavaScript file from the head of the HTML file. Our updated HTML file now looks like this:
To test our D3.js setup we open the inspect element tool kit. In the Element tab of the Webkit Inspector, we open all of the elements so that we can see the whole HTML structure. We then hover over the d3.v5.min.js src.
Here is a simple Code with the use of D3JS library. Just copy paste it into a file and save it in html format ex. index.html or hello.html . You can name the file whatever You like but append .html at the end so that it could be rendered as a valid html file. Open it in a Web browser by double clicking it.
