In this demo, we asynchronously load a text file, use JavaScript to count the number of times each letter appears in that file, and generate a bar chart showing the letter count in D3.js.
This is meant to be an introductory demo to expose students to HTML, CSS, JavaScript, D3.js, bl.ocks.org, and blockbuilder.org for the first time.
