Gapminder Bubble Chart: Online interactive chart data platform

GapMinder: The online interactive chart data platform is a perfect world for converting international statistical data into active, interactive, and interesting charts, based on an interactive chart set of online statistical data. The aim is to promote fact-based world observation by promoting the use and understanding of publicly available statistical data that can be freely accessed.

Gapminder was developed by a Swedish nonprofit organization, and Google bought the unit's statistical analysis software Trendalyzer in March 2007 and included programmers in the Google family. Trendalyzer is a web-based (web-based) interactive statistical data browsing interface. The general estimate is that if the software continues to evolve, it will become an important display platform for Google's "statistics" and allow statistics to be no longer dull, but to live like an animated image.

The development team designed the Gapminder to complete a perfect world of interactive charting based on online statistics. In 2010 they finally overcame the online use barrier, releasing Gapminder to the world in the form of desktop software, which is suitable for all current operating systems.

Gapminder is a software application designed for teachers and students to adapt to global trends, but its pre-loaded 600 data indicators (health, environment, economics, education, poverty, technology, etc.), and the perfect display effect make it in the future will not be confined to the use of education. Can guide the world's different years, population, economic growth rate, carbon dioxide emissions, birth rate, GNP, per thousand people network utilization, defense expenditure and women's labor force.

A bubble chart is a scatter plot that represents a point as a bubble (or circle), similar to an xy (scatter) chart, but can represent more information, representing up to five dimensions (x position, y position, size, color, and time), animating the bubbles by changing the size and color of the bubbles to animate the visual effect To make data exploration more convenient.

On the site http://www.gapminder.org can find a large number of dynamic bubble map applications, but also to do their own operation and adjustment, see the following use Help:

What do you think? Go and experience it! After using it, you might think: Can you download a software to make this animation yourself? In fact, it is by a call trendalyzer Software made out, in March 2007, Google acquired Trendalyzer Software, has not found the software, so want to make the exact same effect is difficult, But you can try Google free Motion Chart Gadget and public Data Explorer, here's an example: World development Indicators and Global development Finance.

SAS JMP software can also make similar effects, see an example of the implementation process, refer to the Software help manual "Discover JMP", using the software comes with the age group. JMP data Sheet, which contains demographic data from 1950 to 2004 in 116 countries. The total population is divided by age groups, and not every year there is data for each country.

Sociologists want to explore the following questions: is the age of the world's population changing? To answer this question, check the relationship between the oldest (59 years old) and the youngest (less than 20 years old) age population. Use a bubble chart to determine how the relationship changes over time.

Create a bubble chart
1. Open the age group. JMP Data Sheet.
2. Select Graphics > Bubble chart.

3. Select the 60+-year-old population ratio and click Y. This corresponds to the Y variable in the bubble chart.
4. Select the 0-19-year-old population ratio and click X. This corresponds to the X variable in the bubble chart.
5. Select the country and click on the ID.
Each unique level of the ID variable is represented by a bubble in the drawing.
6. Select the year and click Time. This controls the time indicator when making bubble chart animations.
7. Select the population and click Size. This controls the size of the bubbles.
8. Select the region and click on the color. Each unique level of the color variable is represented by the color of the bubble. In this example, all the bubbles in different countries in the same region are the same color.
9. Click OK.

Since the time variable ("year" in this example) starts at 1950, the initial bubble chart shows data for 1950. Click Execute to cause the bubble chart to animate the loop for all years. Each successive bubble chart displays data for the corresponding year.

The 1950 bubble chart shows a low proportion of the population over 59 years of age if the proportion of young people under the age of 20 is high.

Click to play a bubble chart animation that changes with the year. Over time, the 0-19-year-old population is smaller than the population, and the population of 60+ is higher than the population. The bubble chart indicates that the world population is getting older.

Click to select a bubble to see its trend over time. For example, in the 1950 graph, the big bubbles in the middle are "Japan". Click in the middle of the "Japan" bubble to select it. From the Red Small Triangle menu, select the Wake bubble. Click Execute. As the animation plays, the "Japan" bubble leaves a bubble wake to demonstrate the bubble's historical trajectory.

Finally, you can save the above animation as a SWF file, embedded in Excel for use, click here to download.

Hans Rosling will perform the dynamic bubble chart incisively and vividly, such as the following 4 minutes: 3D Technology shows 200 countries for 200 years.
