Editor's note: Due to growing interest in the candidacy of Newt Gingrich, we have added him to the interactive. - 12/6/11

Continuing our analysis of campaign finance data from the Federal Election Commission, we have developed a tool to visualize where money donated by Texans to presidential candidates comes from, broken down by ZIP code.

In this first version, we are featuring Gov. Rick Perry, former Massachusetts Gov. Mitt Romney, President Obama and U.S. Rep. Ron Paul. Contribution data used includes funds donated at any point in the 2012 election cycle. Because Perry did not join the race for the GOP nomination until mid-August, his numbers only reflect the third quarter.

So where did each candidate find the most financial support from Texas donors?

Perry received the most support from the Houston-area ZIP code of 77024, with 164 donors giving him a combined $334,175. Just off of Katy Freeway between Katy and Houston, 77024 is home to the towns of Hedwig Village, Piney Point Village and Bunker Hill Village. In Austin, Perry was neck and neck with Obama in the West Austin ZIP codes of 78746 and 78703, home to the neighborhoods of West Lake Hills and Clarksville, respectively. Perry raised $472,000 from 274 donors in both ZIP codes to Obama's $386,000 from 374 donors.

Much like Perry, Romney found most of his support west of Houston, pulling in large sums of donations from the ZIP codes of 77019, 77024 and 77056. He raised $196,000, $177,000 and $146,000, respectively. However, donors were more generous to Perry in all three areas, where he raised $220,000, $334,000 and $199,000.

Click on candidates' names above the map to view their donations. Use the zoom drop down on the left to take a closer look at some of the high-donor cities in the state. To switch between visualizing the amount donated and the number of donors, use the drop-down on the right. If no one from a ZIP code contributed to any candidate, there will be no shape to represent it.
