THE D3.js developer test enables employers and recruiters to identify & hire D3.js Experts or Data Visualization Experts by evaluating working skills and job readiness. For this reason, an emphasis is laid upon evaluating the knowledge of applied skills gained through real work experience rather than theoretical knowledge.
