Your favorite TV shows, such as Breaking Bad, now have the data to back them up that they were exceptionally good shows. The Nielsen Ratings system of today also helps.

As of now, CBS is the No#1 network with adults in the 18-49 demographic in Prime-time, with shows like NCIS and NCIS: LA leading the pack, along with NBC's The Voice coming in at a strong second, according to the Nielsen ratings.

Last week, Graph TV was launched, the latest project by data viz virtuoso Kevin Wu, Wired.com reported. What it does is that it lets you visualize IMDb's massive database of user ratings, and it tabulates what shows actually did well, were consistently good, and for some just caused TV watchers to lose interest.

You type in the name of a show and the site gamely spits out a graph of every episode, helpfully color coding seasons, and drawing a linear regression line for each. No longer will your TV arguments be founded solely on vague recollections and long-held grudges. This is cold hard data. The idea came to Wu when he was watching Breaking Bad.

"I thought the last half of season five was just amazing, and I wondered if people thought the same," Wu said. It's clear that his fellow fans agreed, the chart for the series shows a strong upward slope during the second half of that last season. For Breaking Bad, the graph indicates the seasons started well, and then it ended on an even stronger season, to return with the next season even better.

Other graphs tell stories about the U.S. version of The Office. It had a strong climb in Season 3, when the show was trying to find its voice. But by seasons 4 and 5, it plateaued with a downward slide in season 6.

Also, The West Wing lost viewership after four seasons, this was when writer Aaron Sorkin left the show. And 24 lost its steam after the few beginning seasons, but came back with a strong finale. The show 24, compared to Dexter, had an opposite effect. Dexter plummeted in its final season with a polarizing final episode.

Wu says most of the reactions that he has seen suggest that the graphs line up with the general sentiments of the TV-watching public. "I thought that the knowledge of the crowds are fairly accurate and represent most people's feelings," Wu said.

Is Wu's data a no-brainer, or is it the next step in the Nielsen ratings system, which some people cannot understand, especially when their favorite shows get cancelled and the rubbish that remains on TV? For now, Wu's Graph TV project takes into account real hard visible data.
