Bright and Blind Spots: By Spread

English Portuguese Spanish

This page shows the spread of research across topics and countries. We offer two different ways to analyze this research spread: normality measures and article growth.

• Normality describes how close a topic’s probability distribution is to the standard statistical normal distribution; hover over each plot point to view a topic’s normality measure in relation to all countries and to all documents in the corpus.
• Article growth simply describes the number of water-related articles published per year by socio-hydrologic country groups. Each group consists of countries with similar characteristics (as described on the Country Groups page), which makes it possible to combine the volume of research from related nations. Hover over the black lines to view the year, number of articles published, and country group. To compare multiple country groups at the same time, click the button on the upper right corner of this diagram.

Bright and Blind Spots By Spread: How-To

Each plot has a selection of features on the top right side of the plot. Hover over each icon to display the function name. From left to right, this functionality includes the ability to download the plot as a png, to selectively zoom, pan, box and lasso select, generally zoom in/out, autoscale, reset the axis, and toggle spike lines; there are also buttons to show the closest data on hover and compare data on hover. Double clicking the plot after zooming in will reset it. Downloading the plot as a png will capture the data image within the frame, which may be relevant when zooming in or using the selection features.

Article Growth

Below is a brief breakdown of the different country groups. Please refer to the Country Groups page for more information about how we grouped countries in the study.

• Group 1 is in orange and has the largest growth in volume of water-related research published per year. This group consists of Brazil and Mexico.
• Group 2 is in green and has the second largest volume of research. This group consists of Argentina, Chile, Guyana, Suriname, Uruguay, and Venezuela.
• Group 3 is in blue and has the smallest volume of water research. This group consists of Belize, Bolivia, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Guatemala, Honduras, Jamaica, Nicaragua, Panama, Paraguay, and Peru.
