/**
 * @module Attribution
 * Attribution components display the top 10 total client counts for namespaces or auth methods (mounts) during a billing period.
 * A horizontal bar chart shows on the right, with the top namespace/auth method and respective client totals on the left.
 *
 * @example
 * ```js
 *  <Clients::Attribution
 *    @chartLegend={{this.chartLegend}}
 *    @totalClientsData={{this.totalClientsData}}
 *    @totalUsageCounts={{this.totalUsageCounts}}
 *    @selectedNamespace={{this.selectedNamespace}}
 *    @startTimeDisplay={{this.startTimeDisplay}}
 *    @endTimeDisplay={{this.endTimeDisplay}}
 *    @isDateRange={{this.isDateRange}}
 *    @timestamp={{this.responseTimestamp}}
 *  />
 * ```
 * @param {array} chartLegend - (passed to child) array of objects with key names 'key' and 'label' so data can be stacked
 * @param {array} totalClientsData - array of objects containing a label and breakdown of total, entity and non-entity clients
 * @param {object} totalUsageCounts - object with total client counts for chart tooltip text
 * @param {string} selectedNamespace - namespace selected from filter bar
 * @param {string} startTimeDisplay - start date for CSV modal
 * @param {string} endTimeDisplay - end date for CSV modal
 * @param {boolean} isDateRange - getter calculated in parent to relay if dataset is a date range or single month
 * @param {string} timestamp - timestamp response was received from API
