Humans are remarkably attuned to pattern matching. It's the result of thousands of years in evolution. I see this on a daily basis with my children as they play with their toys. They're constantly finding new ways to place blocks in a location that's nearly impossible for me to reach. But, I digress.
They say that a picture is worth a thousand words. This is especially true when it comes to data. When faced with rows upon rows of seemingly meaningless data, we often turn to visualizations like charts and graphs to help make sense of it.
For years, I've been fascinated with data visualization – especially beautiful ones. Chances are, if you've picked up a newspaper or visited a news site like the New York Times, you've found yourself staring at one. They're everywhere these days. And for good reason too! Good data visualization allow us to interpret data is new and powerful ways. This opens up the world around us to a wealth of knowledge that went unseen in the past.
Armed with Kendo UI DataViz, I felt compelled to share information with folks in the developer community about a growing concern of mine; the weight of web pages or, what I like to call "webpage obesity".
In terms of bytes-on-the-wire, the Internet is getting fat. Quite fat, in fact. For example, did you know that an average webpage is around 1.4 MB? Not surprised? You should be. "But, why should I care?" you may ask. The reason is simple: performance.
Recently, I posted a copy of a fantastic infographic by Strangeloop Networks, which cites a number of statistics concerning website performance and the impact it has on a company's bottom line. Basically, it boiled down to this: if your website is slow, your customers won't want to come back.
Anyway, getting back to my love affair with data visualization.
The HTTP Archive is a fantastic resource for web developers wanting to discover how sites tick. Every two weeks, it crawls over 290,000 URLs, collecting information on each one. It provides a historical log of this information for developers to sift through. Its mission is articulated as such:
In addition to the content of web pages, it's important to record how this digitized content is constructed and served. The HTTP Archive provides this record. It is a permanent repository of web performance information such as size of pages, failed requests, and technologies utilized. This performance information allows us to see trends in how the Web is built and provides a common data set from which to conduct web performance research.
The HTTP Archive provides some nice charts and graphs, but each time I visited the site, I always felt like I wanted more insight into the data. And thus, my side project entitled, Webpage Obesity was born.
