Another Stab at the Perfect CSS Pie Chart… Sans JavaScript!

This article explores building semantic pie charts using CSS without JavaScript by moving data to parent elements.

• •Moves percentage values from individual list items to the parent ul element, enabling CSS-only computation of slice positions and accumulations
• •Uses CSS attr() function with the upgraded type syntax to read data-percentage attributes into custom properties
• •Implements nth-child() selectors combined with CSS calc() to compute cumulative percentages (--accum values) for each slice
• •Maintains semantic HTML structure with accessibility for screen readers while keeping markup easy to customize
• •Eliminates JavaScript entirely by leveraging CSS custom properties and inheritance from parent to child elements
