Learn Data Visualization in This Free 17-Hour Course

Business is becoming increasingly data driven and this data needs to be visualized to make it easier to understand. Data Visualization is a growing field with many opportunities.

We've released a comprehensive 17-hour course on data visualization that is perfect for anyone new to the field. The course focusses on visualizing data using D3.js, JavaScript, and React.

Curran Kelleher developed this course. Curran previously created one of the most popular data visualization courses on the internet and now he has completely redone and improved the course. This course comes out of his extensive experience developing data visualizations and teaching new developers.
