Update: This post has been updated based on valuable feedback from the #SWDchallenge community. The changes include:

Reordering the table by Sales Volume to bring Account J, which has the largest negative percentage change, to the top for better emphasis.
Adjusting the color scheme to differentiate between positive and negative growth values more clearly, ensuring a more intuitive visual representation.
Highlighting Accounts J and H to emphasize the largest decrease and the highest growth, respectively.

The goal of this month’s Storytelling with Data challenge is to apply emphasis to the table shown below.

Makeover

Figure 2: Here is the WakeUp Coffee Sales Summary for the top 10 accounts by sales volume for the 4 weeks ending January 31st. Account H experienced the highest growth (+37.90%) with sales totaling $11,645. Account D had the highest sales volume at $547,265. Accounts J and E both showed significant declines, with -8.70% and -4.70%, respectively. The table includes sales volume, percentage change versus prior period, average number of UPCs, percentage of ACV selling, and price per pound.
