Explore relationships between variables with this animated scatterplot, which uses colors to identify regions and size to represent national populations. The play button reveals how the relationship has evolved historically.

  • Chart Options

    Color: The color of the bubble is set by choices in the dropdown menu under "color". By default, colors are differentiated by region. 

    Size: The size of the bubble is also set by options in the dropdown menu under "size". 

    Countries: Selecting countries under the "select" list will highlight them on the chart by lowering the opacity of the other country bubbles. Opacity can be set by clicking on the wrench icon in the lower right hand corner. Countries are greyed out in the list if there is no charted data for those countries for the selected variables. Hovering over the bubbles will display the country name and x and y data values. 
    Trails: Checking the "trails" box will add a line to the selected countries that will trail that country's progress over time, connecting the points. 

    Bubbles vs. Lines: The tabs on the upper right hand side of the chart offer different ways of viewing the data in both vertical and horizontal linear format. 

    Lin vs. Log: By default, the chart is set to linear scale. Data can also be viewed in a logarithmic scale by selecting the "lin" button on the upper left hand side and switching to "log".

  • Interpreting Charts

    We display details regarding the construction of V-Dem indicators and indices in the "Selected Indicators" box at the bottom of the page.

    Tip! The V-Dem Codebook includes a table entitled ‘Structure of Aggregations – All Indices and Indicators’. This table displays how indicators, components and indices are related, which is helpful for understanding the structure of aggregation.

  • Tip!

    You can hide the menu for the selection of countries and indicators by pressing the arrow in the top right corner of the box.

    In "Selected Indicators" click on an indicator to expand the question text and answer choices.
