* Update d3-format to v1.2 * [Feature] Adds support for optional "percent" suffix in locale definition. * Added tslint.json file * [d3-array] Update to version 1.2 * [Feature]: Add `tickIncrement(...)` * [Fix]: Fix incorrect return type of tickStep(...). The correct return type is `number` instead of `number[]` * [Chore]: Updated related comments * [d3] Update minor version to 4.8 * Fix d3-format related linting errors.
