This example shows a horizontal bar chart comparing the 2010 population of 20 countries, with each bar labeled by country name and value. Population data is loaded from a GitHub-hosted CSV file via d3.csv, then converted from thousands to raw numbers. The chart is built with React components, using d3.scaleBand and d3.scaleLinear for positioning, SVG rectangles for marks, and d3.format to display tick labels with abbreviations like “1.2B.” Native SVG `<title>` elements provide tooltips on hover.

This bar chart displays the population of ten countries in the year 2000, using a horizontal layout with country names on the y-axis and population values on the x-axis. The visualization is built with React and D3 v5, using `scaleBand` and `scaleLinear` to map data to SVG rectangles, with hover tooltips provided by the `title` element. Data is loaded via `d3.csv` from a GitHub-hosted CSV file, and axes are rendered through custom components.

Fork of Activity_6_Task_1_Question_1_1

This example shows a horizontal bar chart comparing the population of ten countries in the year 2000, sorted by country name. The chart uses React components to render SVG elements, with D3’s `scaleBand` and `scaleLinear` handling the layout, while `AxisBottom` and `AxisLeft` generate the axes. Data is loaded using `d3.csv` from a remote GitHub CSV file, and each bar displays a native tooltip with its formatted population value.

This bar chart displays the population of 20 countries in 2010, sorted alphabetically along the vertical axis with horizontal bars extending to population values. The visualization uses React with D3 v5 modules including scaleBand, scaleLinear, and format to construct the SVG. Data is loaded via d3.csv from a GitHub-hosted CSV file, with the raw ’2010’ values multiplied by 1000 to represent actual population counts. Green bars include native SVG `<title>` tooltips showing formatted population values, while axis ticks and labels are styled with custom CSS.

Fork of Activity 6-Task1Question1

This example presents a horizontal bar chart of population figures for 30 countries in 2020, with each bar’s length encoding the population value and the y-axis listing country names. Built with React and D3 v5, it uses `scaleBand` and `scaleLinear` to map data to SVG rectangles, `format('.2s')` to abbreviate axis ticks (converting G to B), and a `<title>` element for hover tooltips. Data is loaded from a remote CSV via `d3.csv`, and the chart is rendered entirely as SVG with custom axis components.

Fork of activity_6 Task1

This example displays a horizontal bar chart of population figures for 20 countries in 2010, with country names on the y-axis and population counts on the x-axis. The visualization is built with React and D3 (scaleBand, scaleLinear, format), rendering SVG rectangles for bars and custom axis components. Data is loaded from a CSV file via d3.csv and parsed to numeric population values.
