This example shows the population of the ten most populous countries in 2018, based on United Nations estimates. It uses d3.csv to load the data, d3.scaleLinear for the horizontal axis, and d3.scaleBand for vertical country categories. The bars are rendered as SVG rectangles, with d3.axisLeft and d3.axisBottom creating the axes. Population values are multiplied by 1,000 before being drawn, and the chart is laid out with fixed margins inside a 960-by-500 SVG.

AI-generated description

This bar chart shows population of the top 10 most populous countries. The data comes from the year 2018 estimate in United Nations: World Population Prospects 2017.

Making a Bar Chart

This example displays the population of the ten most populous countries, based on 2018 United Nations estimates from World Population Prospects 2017, as horizontal bars. The chart uses D3 v5 with `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the y-axis, and `d3.axisLeft` and `d3.axisBottom` for tick rendering. Data is loaded from a CSV via `d3.csv`, and each bar’s width is scaled proportionally to population values, multiplied by 1000. The SVG output is styled with steelblue rectangles.

Making a Bar Chart

This example presents a horizontal bar chart of the populations of the ten most populous countries, based on 2018 estimates from the United Nations World Population Prospects. The visualization uses D3 v5 to load a CSV file with `d3.csv`, then scales the data with `scaleLinear` for the x-axis and `scaleBand` for the y-axis. Axes are generated with `axisLeft` and `axisBottom`, while bars are appended as SVG `rect` elements. Population values are multiplied by 1,000 before rendering.

Making a Bar Chart

This bar chart displays the populations of the ten most populous countries, based on 2018 United Nations estimates from the World Population Prospects. The data, loaded from a CSV file, is scaled using d3.scaleLinear for the horizontal axis and d3.scaleBand for the categorical vertical axis. The chart renders as SVG rectangles, with population values parsed from strings to numbers and multiplied by 1,000 before being mapped to bar widths. The visualization uses D3 v5, focusing on a clean, margin-less layout within a 960×500 SVG canvas.

Making a Bar Chart

This bar chart displays the population of the ten most populous countries, using 2018 estimates from the United Nations’ World Population Prospects. The data is loaded from a CSV file via `d3.csv`, with population values multiplied by 1,000. The visualization is rendered as an SVG using D3 v5, employing `scaleLinear` for the x-axis, `scaleBand` for the categorical y-axis, and `axisLeft`/`axisBottom` to draw the axes. The bars are appended as `rect` elements, with their width and height calculated from the scales.

Making a Bar Chart

This bar chart displays the populations of the ten most populous countries, using 2018 estimates from the United Nations World Population Prospects. The visualization pairs a linear scale for population values with a band scale for country names, rendering horizontal bars in SVG. Built with D3 v5, the code uses `d3.csv` to load the data, `scaleLinear` and `scaleBand` for scaling, and `axisLeft` and `axisBottom` to draw the axes. Population figures are multiplied by 1000 to reflect actual counts.

Making a Bar Chart

This bar chart displays the population of the top ten most populous countries, based on 2020 estimates from the UN World Population Prospects. It uses d3.csv to load data from a local CSV file, d3.scaleLinear for the population axis, d3.scaleBand for the country categories, and d3.axisLeft and d3.axisBottom to render the axes. The chart renders population values as horizontal bars in SVG, with each bar’s width proportional to the population count, which is multiplied by 1,000 after parsing.

Making a Bar Chart

This example displays the populations of the ten most populous countries in 2018, ordered along a vertical bar chart. It uses D3 v5’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to map population values to horizontal bar widths and country names to vertical bands. The data, sourced from the United Nations’ 2017 World Population Prospects, is loaded via `csv` and rendered as SVG rectangles. The code explicitly multiplies population figures by 1,000 to reflect actual counts.
