 * @param {object} weightLiftedRecord - the user's weight lifted record object
 * @returns {array} - an array of objects that can be used to create a graph of the user's weight lifted progress over time
 * @description - This function will take in the user's weight lifted history (record) and return an array of
 * objects that can be used to create a graph of the user's weight lifted progress over time.
 * The function should return an array of objects, in which each object represents a weight lifted record,
 * if there is no record for a date, the weight lifted record for that date should be 0
 * The first record will have the same weight lifted as the first record.
 * If the weight lifted record is empty, the function should return an empty array.
