In North America, the division between E and W variation runs on an isogonic line, often referred to as the agonic line, which roughly extends from Minneapolis/St.
These lines are called "isogonic lines" unless it is indicating a zero variation, then it is called an "agonic line." A pilot uses these lines to correct the true course he drew on a chart for variation.
