This example visualizes the 2020 populations of 20 countries as a horizontal bar chart, using SVG rectangles rendered through React components. It loads data from a GitHub-hosted CSV file via d3.csv, then maps each country’s population (converted from thousands) to bar widths using d3.scaleLinear, while d3.scaleBand positions the categorical y-axis labels. D3’s format method abbreviates large numbers, and custom AxisBottom and AxisLeft components generate styled ticks. The chart is built with React functional components and d3 v5, featuring green bars and blue tick lines.

Fork of Activity6_Question 1.2

This example displays a horizontal bar chart comparing the populations of 20 countries for the year 2010, using a bright green fill for the bars. The React application loads data from a remote CSV file via `d3.csv` and renders the visualization as an SVG. It uses D3 v5's `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis, with custom `AxisBottom`, `AxisLeft`, and `Marks` components. A tooltip showing the population in billions appears on hover, driven by the `<title>` element within each bar.

Fork of Activity 6_Question 2

This example presents a horizontal bar chart of population figures for 20 countries in 2020, arranged from top to bottom by country name. The chart uses React components to render SVG elements, with D3 v5’s `scaleBand` and `scaleLinear` for positioning bars and `format` to abbreviate axis tick labels. Data is loaded from a remote CSV using D3’s `csv` function, with population values computed by multiplying the 2010 column by 1000. Bars include a native SVG `<title>` tooltip showing the formatted population value.

Activity6Question2

This example displays a horizontal bar chart of population figures for 20 countries in 2020, using CSV data loaded from a GitHub repository. React renders SVG elements, while D3 v5 handles scales and formatting: `scaleBand` maps countries to y-axis positions and `scaleLinear` maps population values to bar widths. The chart includes formatted tick labels that convert values to billions (e.g., "G" replaced with "B") and native SVG `<title>` elements for tooltips. Reusable React components (`AxisBottom`, `AxisLeft`, `Marks`) structure the visualization.

This example shows the population of 20 countries in 2010 as a horizontal bar chart. The chart uses D3’s scaleBand and scaleLinear to map countries to y-axis positions and population values to bar widths, rendered as SVG rectangles. React manages the component state and lifecycle, while D3’s csv function loads the population data from a GitHub-hosted CSV file. Axis components generate tick marks and labels, and a tooltip displays the formatted population value for each bar.

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 Q1.1

This bar chart shows the population of ten countries in the year 2000, with countries listed on the y-axis and population values on the x-axis. The code uses React components to render SVG elements, including custom AxisBottom and AxisLeft components for ticks and labels. It loads CSV data from a GitHub repository using d3.csv, then applies a linear scale for population and a band scale for countries. The bars are green rectangles with tooltips showing formatted population values, and the x-axis labels use d3-format to abbreviate large numbers.

Fork of Activity-6_Question1.2

This horizontal bar chart displays the population of the first 20 countries in 2010, with countries listed on the y-axis and population values on the x-axis. The visualization uses React with D3 v5 to load data from a CSV file, and renders the bars as SVG rectangles. The code uses d3.scaleBand for the y-axis, d3.scaleLinear for the x-axis, and a custom d3.format('.2s') to abbreviate population values, while tooltips show the exact formatted values.

Fork of Activity-6 Q1.2

This visualization shows a horizontal bar chart of 2020 populations for 20 countries, ordered by country name, with green bars and blue tick lines. The React app loads data from a CSV file via `d3.csv`, then uses `d3.scaleBand` for the y-axis and `d3.scaleLinear` for the x-axis, rendering SVG rectangles with `<title>` tooltips. Axes are drawn with custom components, and tick labels use `d3.format` to abbreviate values (e.g., "B" for billions).
