A word cloud of whole phrases, each in its own colored box and sized by how often it comes up. Here, what a café’s customers say most in their reviews.
Single words lose their meaning out of context: "line" or "loud" say little alone. Short phrases keep it, and their boxes make each one easy to pick out. It works for a handful of phrases, such as the themes found in reviews or a survey.
Built with amCharts 5, a JavaScript library. The JavaScript includes your theme and renderer (canvas or SVG); the JSON also follows the changes you make with the controls.
npm install @amcharts/amcharts5. See Getting started.
The same chart as a JSON config. Chart Maker reads and writes this format, the library's JSON parser turns it into a chart, and the <am5-chart> element puts it on a page with no code."type" is the class to create and "settings" what you would pass to its new() in code; "properties" fill in its parts, lists such as series and axes or templates such as columns.template; "refs" holds objects used in more than one place ("#series-0" stands for the one named series-0); a string starting with "@" takes a value from another object, such as "@series.get('fill')".
A complete page. Save it as an .html file and open it in a browser.
Paste this into an AI coding assistant to build the chart from scratch. More in amCharts & AI.
