Interactive chord diagram to visualize trade

Siddhesh Kaushik's picture

What comes to mind when we think of trade? Quite possibly, exports, imports and trade balance. Is there a quick way to get this information without having to look at tables? Most of us would like to see how much a country imports and exports, which are the major trade partners, and what is the trade balance. We have introduced a d3.js based interactive Chord diagram to quickly visualize this information.

For example, here is a visual of Australia’s Exports and Imports for 2015. The chart shows top countries to which Australia exported or imported that year, and the remaining are bundled as “others”. Here is how you can interpret the diagram.

Each country has a different color. The length of the arc for Australia represents Australia’s total imports and the other parts of the arc show Australia’s exports to various countries. We can see the Import arc is slightly bigger than the Export arc and hence Australia has an overall negative trade balance.

Latest from the LSMS: The Crowd & The Cloud, debunking myths about African Agriculture & costing household surveys

Message from Gero Carletto (Manager, LSMS)

I would like to take this opportunity to remember Hans Rosling, a friend and supporter of the LSMS. I don’t need to tell you about his contagious enthusiasm for data or his masterful use of visualization tools to communicate statistics. I can’t say I knew Hans that well, but over the years, even if only based on sporadic interactions, I came to appreciate him both as a person and a scientist. I met him for the first time in 2013 and still remember the flabbergasted look on his face when Kathleen Beegle and I told him that the core LSMS team consisted of only four part-time staff. He was astounded to find out that we were so small, yet we looked so big. And, of course, being the visualization maestro that he was, he immediately came up with his own visual representation of the LSMS with a tool he had at his disposal at that moment: his hand!

From that day on, every time we met, he greeted me with his "LSMS hand." To this day, it remains a good, and fun, memory of Hans.

From data blur to slow-mo clarity: big data in trade and competitiveness

Prasanna Lal Das's picture

Tolstoy's War and Peace was the big data of its time. A memorable moment from the epic novel occurs when Prince Andrei awakens following a severe injury on the battlefield. He fears the worst but, "above him there was nothing but the sky, the lofty heavens, not clear, yet immeasurably lofty, with gray clouds slowly drifting across them. 'How quiet, solemn, and serene, not at all as it was when I was running.'" Time appears to slow down and the Prince sees life more lucidly than ever before as he discovers the potential for happiness within him.

In many ways the scene captures what we demand of big data—not the bustle of zillions of data points as confusing as the fog of war, but sharp, clear insights that bring the right information into relief and help us connect strands previously unseen. The question of whether this idea is achievable is the starting point of a paper about big data on trade and competitiveness just published by the World Bank Group. In it, we asked—can big data help policy makers see the world in ways they haven't before? Are decisions that are informed by the vast amounts of data that envelop us better than decisions based on traditional tools? We didn't want a story trumpeting the miracles of big data; we wanted instead to see the reality of big data in action, in its messiness and its splendor.

Open source software: addressing some misconceptions and stereotypes

Alanna Simpson's picture

While stuck in I-66 traffic one morning, a colleague and I had a vigorous debate on the merits of open-source versus proprietary software. I was left with the realization of how much misinformation still persists about this particular subject.

This discussion prompted me to be more proactive about advocating for the adoption of open-source technology. I believe we are just beginning to explore the possibilities for these tools in reducing poverty and ensuring sustainable development.

Between 2 Geeks: Episode 1 - The ups and downs of demography

Tariq Khokhar's picture

Between now and 2050, Africa will add over 1 billion people to its population.

That’s a startling statement about something that’s 30 years in the future. One group with a record of making such long-range projections is demographers like Dr. John May with the Population Reference Bureau.

In our discussion with John, he explains that the growth and structure of populations is linked to one fundamental issue: mortality rates. When infant and child mortality rates decline, fertility rates also eventually decline and population growth slows down. And as life expectancies increase, the share of older people in a country’s population goes up.

But it turns out things are a bit more complicated than that, and there are large implications for public policy that are ultimately driven by demography.

Even when a region like Africa has declining fertility rates, “population momentum” means that countries will continue to grow. With this growth comes the need for better infrastructure, services, and crucially, jobs.

By one estimate, the global economy will need to add 600 million jobs over the next 10 years - mostly in Africa and Asia - just to keep up with young people entering the workforce.

So how is demography shaping our future, and how can we make it the future we want?

Nearly 1.1 billion people or 15 percent of the world’s population had no access to electricity in 2014. Nearly half were in rural areas of Sub-Saharan Africa, and nearly a third were rural dwellers in South Asia. In all, 86 percent of people without electricity lived in rural areas, where providing infrastructure is more challenging. Read more in the Global Tracking Framework and their 2017 report on progress towards sustainable energy. 

Between 2 Geeks: A new podcast about data and development

Tariq Khokhar's picture

I find data to be a great way of getting into a subject.

Take forests for example. Making this map  about where forests have been lost and gained since 1990 led me down a wonderful rabbit hole of learning about China’s successful reforestation programs, how forests support people’s livelihoods, the definitions of what counts as a forest (hint: it’s not just “a bunch of trees”), and how organizations use a variety of sources from nationals surveys to satellite imagery to produce this data.

Not only is there a story behind every number, but numbers can help to tell the story of development.  

That’s the idea behind a new podcast - “Between 2 Geeks” in which Raka, Andrew and I, talk to folks who create and use data, as they work across the field of international development.

We’ve got a great lineup of guests, and discuss topics including Africa’s “demographic dividend” - how population structures are shaping the future of the region; a new risk insurance mechanism designed to help stop pandemics like the 2014 West African Ebola outbreak; and how metadata from cell phone networks can be used to estimate measures of migration and poverty.

Just like the forest map, I’ve found each episode to be a peek into the rabbit hole of a new subject - I’ve learned how to better communicate about uncertainty, the economics of large scale renewable energy systems, and what the future of how data is produced and used may look like.  

We’ve really enjoyed making the first series of this podcast and we hope you’ll tune in. The opening episode will be available on Tuesday April 4th - it’ll be posted here on The Data Blog, on the World Bank’s SoundCloud channel, and you can subscribe to “World Bank’s Podcasts” in your podcast app or on iTunes.

 

Special Issue of Food Policy Debunks Myths about African Agriculture

Vini Vaid's picture

In this era of alternative facts, the use of high-quality data to set the record straight is more important than ever. In Africa, there has been a pressing need to revisit the conventional wisdom on the region’s agriculture. However, relevant data—where available—have long been outdated and inadequate.

With this in mind, the World Bank’s Africa Chief Economist Office and its partners initiated the Agriculture in Africa– Telling Facts from Myths project. It explores the validity of the conventions surrounding Africa’s agriculture and its farmers’ livelihoods that experts and policymakers considered as self-evident truths. The impact of such stylized facts cannot be underestimated. They shape the policy debates and drive research agendas

Now, a Special Issue of Food Policy brings together 12 open-access articles based on the project, drawing mainly on data from the first rounds (2009–2012) of the nationally representative Living Standards Measurement Study-Integrated Surveys on Agriculture (LSMS-ISA). Four innovative features of the LSMS-ISA data—integration, individualization, ICT use, and intertemporal tracking—allowed for a more refined insight into African agriculture and rural livelihoods.

Chart: Globally, 70% of Freshwater is Used for Agriculture

In most regions of the world, over 70 percent of freshwater is used for agriculture. By 2050, feeding a planet of 9 billion people will require an estimated 50 percent increase in agricultural production and a 15 percent increase in water withdrawals.
