Two-part comparison showing traffic dashboard redesign. Top image: "Before" - cluttered interface with multiple tabs (Overview, Volume, Speed, Vehicles, Data), numerous sidebar controls, and scattered KPI boxes showing 396,077 total volume, 41.7 avg speed, 3.8% large vehicles. Multiple charts compete for attention across a tabbed layout. Bottom image: "After" - clean single-page design with streamlined sidebar (3 controls only), prominent KPIs at top (28,906 avg daily volume, 44 mph median speed, 3.8% large vehicles), and two focused charts: daily traffic volume trend and weekday vs weekend hourly profile comparison.

The data comes from Kaggle via Sourav Banerjee. This #viz is about Family Guy, an animated sitcom, seasons 1 – 21.

#dataviz | #rstats | #ggplot2
The image combines two scatter plots that depict the correlation between the viewership and IMDb ratings for the TV show Family Guy during its first 21 seasons. Each plot uses the season number as the x-axis, ranging from 1 to 21, and individual episodes of the show are represented as dots. The top chart tracks viewership in the US, plotted on the y-axis from 0 to 20 million viewers. A noticeable trend is that viewership was highest during the early seasons, peaking at 22 million viewers in the first episode and gradually declining over subsequent seasons. Notable episodes are highlighted, such as the series premiere "Death Has a Shadow" and "The Manchurian Candidate" from season 21. The bottom chart displays IMDb ratings, which are plotted on the y-axis from 4 to 10. This plot shows that ratings fluctuated but generally remained stable, averaging around the 7 to 8 range. The episode "Road to the Multiverse" from season 8, which scored 9.1, is highlighted.
