You started a interesting series for Steemit stats. My suggestion are the following points

• white chart background
• make a split maybe in two charts for better readability of the numeric values, for example the top dashed line has a huge range between 10,000 and 100,000, if that represents the Daily Unique Visitors (i'm not sure) it's one of the most important numbers for me i'm curious what's the exact number today
• more clarity between legend and chart lines for clear allocation
• feature to view the exact values today for each graph (especially daily unique visitors)

Everything seems flat since June from what i see here. Thank you for the information!
