D3.js vs. Highcharts

D3 (or D3.js) is a free, open-source JavaScript library for visualizing data. Its low-level approach built on web standards offers unparalleled flexibility in authoring dynamic, data-driven graphics. For more than a decade D3 has powered groundbreaking and award-winning visualizations, become a foundational building block of higher-level chart libraries, and fostered a vibrant community of data practitioners around the world.

Highcharts is a multi-platform charting library that makes it easy for developers to add interactive charts to web and mobile projects of any size. Over 80% of the 100 largest companies in the world use Highcharts, and over 50,000+ companies across industries such as application development, publishing, data science, and finance. Highcharts has been in active development since 2009 and remains a developer favorite due to its robust feature set, ease of use, thorough documentation, accessibility compliance, and vibrant community.
