Visualizing #NICAR18, Part II

I posted recently about the NICAR journalism conference, held this year in Chicago — and it turns out news nerds like to tweet. To keep track of all the conference chatter, I dumped each mention of the #NICAR18 hashtag using Python, eventually collecting some 4,100 tweets. I used #nicar18 several times. Others were even more prolific. Here are those with more than 10 uses during the conference: Next, I created a...

Visualizing the News Nerd Conference Known as #NICAR18

I’m in the United States this week to attend the annual news nerd conference known as NICAR, a diverse gathering of reporters, editors and developers (and others) focused on storytelling with data. I look forward to it like Christmas. I get to return to the United States, see old friends, learn new skills and drink Diet Coke, which is nearly impossible to find in South Korea, where I work as...

Which Countries Sent the Most Athletes to Pyeongchang?

Because I live in Seoul and work as a journalist, I’m paying close attention to the Winter Olympics as they open tonight in Pyeongchang, South Korea. I don’t know much about the Winter Games’ history, so I decided first to research which countries are here. Europe dominates: Here’s a world map (Russia has many athletes here, but they’re not eligible for medals because of a doping scheme): And a table,...

Mapping the United States’ Korean Population

I’ve often felt fortunate that I get to write about South Korea for the Los Angeles Times, a newspaper that’s still interested in stories related to life, politics and culture here — not just the strongman to the North. That interest is in part because the Times remains a serious paper that’s trying to stay committed to foreign news, but also because a decent portion of its readers are Korean. The...

Visualizing More Than a Decade of North Korean Defections

Another North Korean soldier defected at the Demilitarized Zone on Thursday, causing a brief skirmish along the highly fortified border. He was the fourth solder to defect this year, including the one last month who was shot several times by his comrades before he made it to safety in South Korea. There have been tens of thousands of defections from the communist regime since the 1953 armistice that ended the...

Testing ai2html on a North Korean Defector

A few weeks ago I wrote about the daring defection — and eventual rescue — of a North Korean soldier who barreled across the Demilitarized Zone in a truck and then ran as fellow troops fired on him. The story centers on a dramatic video of the ordeal released by United Nations command. The video, shot the afternoon of Nov. 13, shows the soldier speeding down a road toward the...

Choosing color palettes for choropleth maps

Choropleth maps, the ones where regions are filled with colors based on data, grow easier to make. However, choosing colors, the number of colors, and the breakpoints is often less straightforward, because the answer is always context-specific. Lisa Charlotte Rost, now at Datawrapper, provides a rundown of the decision process. The explanation is in the context of the Datawrapper tool, but you can easily apply the logic to your own...

Visualizing North Korea’s Missile Launches

Despite international objections, North Korea has launched four ballistic missiles in the last week, including one that flew over Japan, raising regional tensions about the rogue state’s weapons development even higher. For those of us who live in South Korea, such provocations have become commonplace, especially since the North’s new leader, Kim Jong Un, took over after his father’s death in late 2011. They interrupt Sunday breakfasts or even national...

Teaching Data Journalism In China

I’ve just returned from a week in China, teaching data journalism to students from all over the country at Fudan University (sponsored by the U.S. China Education Trust). Helped by a fabulous co-instructor, Yan Lu, we taught them about acquiring data, data wrangling, storytelling, visualization, SQL, mapping, news apps and more. The students, working journalists and professors, were quite impressive. Working in groups, they created several data-driven projects of their...

Adjusting map data with Mapshaper

Map making is a finicky challenge where oftentimes your map data — points, lines, and polygons — must align just right with your external data that exists as a CSV file or related. Mapshaper is an online tool that helps you massage your geographic data to where it needs to be. The online application has been around for a while, but I only recently used it, and it’s kind of...
