An example of an SVG interaction layer over a canvas rendering layer. This example has 7637 data points from the USDA Nutrition Dataset. Uses requestAnimationFrame to prevent path rendering from locking up the UI. '''NEW''' support for ordinal dimensions!
Interactions done with the brush component
Based on d3.js Parallel Coordinates
Changes:
- Map over each dimension. Assign quantitative scales to all dimensions where every value is a number or null. NOTE!: +"" = 0 AND parseFloat("") !== "". When setting the domain of a quantitative scale. Make sure to coerce "" or nulls to an appropriate value.
