A horizontal bar chart displays population growth rates for 35 countries, with bars extending from a central zero line and colored along a diverging red-yellow-green scale to distinguish negative from positive growth. The chart ranks countries by annual growth percentage, from the United States at 1.05% down to Germany at -0.35%, and includes country labels positioned beside each bar. The visualization uses d3.csv to load data, d3.scaleBand for the categorical y-axis, d3.scaleSequential with d3.interpolateRdYlGn for the diverging color scale, and d3.legendColor to render a horizontal legend. SVG rectangles represent the bars, with axes and labels drawn using d3.axisBottom and SVG text elements.

AI-generated description

Used random values to create a CSV file that contained countries population growth.

I also used https://bl.ocks.org/tlfrd/187e45e0629711c4560cf6bcd0767b27 as reference to build the chart but then utilized different csv data, added different color scale, and legend.

A6_BarChart with Diverging color scale

This bar chart visualizes population growth rates across countries, with a diverging color scale that encodes both magnitude and direction of change. The chart sorts countries from lowest to highest growth rate, using a red-yellow-blue diverging palette from `d3.scaleDiverging` with `d3.interpolateRdYlBu`. Negative rates appear in blue tones, positive in red, with bars extending in opposite directions from a central zero line. The visualization uses D3 v7 with SVG rendering, employs `d3.scaleBand` for categorical x-axis placement and `d3.scaleLinear` for the y-axis, and includes a legend built with the d3-legend library.

d3 bar diverging

This example shows a diverging bar chart of United States rural population growth from 2000 to 2009, using a diverging color scale from ColorBrewer to distinguish positive and negative growth values. The visualization loads CSV data from a GitHub gist, which is based on the Corgis global development dataset, and renders it as SVG bars using D3 v7. The chart uses `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the categorical year on the y-axis, and a `d3.scaleDiverging` with the RdBu color scheme for encoding value magnitude. The d3-legend library adds a sequential color legend, while axis labels and ticks are generated with standard D3 axis methods.

Making a Bar Chart

This bar chart displays population figures for 18 countries, with each bar’s length representing population in thousands and countries ordered along the vertical axis. The visualization uses D3 v5’s `scaleLinear` and `scaleBand` to map data to pixel coordinates, while `axisLeft` and `axisBottom` generate the labeled axes. Population data is loaded from a CSV file via `d3.csv`, and rectangles are appended to an SVG canvas, styled with a purple fill. The chart’s margins and inner dimensions are computed dynamically from the SVG’s width and height attributes.

A6 Diverging Color Scale Bar Chart

This example visualizes life expectancy in 1960 for a selection of countries using a diverging color scale bar chart. The bars are colored on a green-to-red gradient via a sequential scale with an RdYlGn interpolator, where higher life expectancies appear greener and lower ones redder. The chart uses D3 v7 to load data from a CSV file, create SVG bars with band and linear scales, and render axes with tick labels. A custom legend and axis titles are added using D3’s selection and axis methods, while the underlying data is sourced from a shortened TidyTuesday dataset.

Making a bar chart

A horizontal bar chart displays population figures for nine countries, using data from a CSV file. The chart ranks countries by population along a linear scale, with country names on a band scale for bar positioning. Built with D3 v6, the visualization loads CSV data, converts population values to numbers, and renders SVG rectangles. It uses `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to construct the axes and bars, with steelblue fills and margins for layout.

Making a Bar Chart

A horizontal bar chart displays population counts for ten countries, with bars sorted by value from largest to smallest. The visualization uses D3 v5’s `scaleLinear` for the x-axis, `scaleBand` for categorical y-axis spacing, and `axisLeft`/`axisBottom` for tick marks. Data loads from a CSV file via `d3.csv`, with population values multiplied by 1000. SVG rendering positions rectangles with attributes set from the scales.

bar graph

A horizontal bar graph displays population counts for four countries using D3 v6. The visualization renders as SVG, with steelblue bars representing each nation's population, sorted alphabetically by country name. The chart reads population data from a CSV file, multiplies the values by 1000, and uses D3's `scaleLinear` for the x-axis and `scaleBand` for the categorical y-axis. Axes are generated with `axisLeft` and `axisBottom`, while the bar rectangles are appended dynamically to the SVG group.

Activity6_Task1_Q1.2

A horizontal bar chart shows the populations of 20 countries in 2010, sorted by country name, with each bar’s length scaled linearly by population and labeled with a shortened numeric format that converts millions to billions. The chart uses D3 v7’s `d3.scaleLinear`, `d3.scaleBand`, `d3.axisBottom`, and `d3.axisLeft` to construct the axes and marks, with SVG rectangles drawn via `Marks.js` and data loaded from a remote CSV using `d3.csv`. The visualization highlights the relative population magnitudes across countries with a light green fill and blue tick lines.
