Forked from Activity 7

This example visualizes the 2020 population of 30 countries using a horizontal bar chart. The SVG renders through React components, with d3.scaleBand positioning countries on the y-axis and d3.scaleLinear mapping population values to bar lengths on the x-axis. Axis tick labels use d3.format with the '.2s' specifier to abbreviate values, replacing 'G' with 'B' for billions. The data is loaded asynchronously via d3.csv from a GitHub-hosted CSV file, with each bar including a native SVG tooltip showing the formatted population value.

Fork of Activity 7

This visualization shows the population of thirty countries in 2020 as a horizontal bar chart, with a title labeling the x-axis "POPULATION-2020". It uses React to render an SVG and the D3 v5 library's `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis. D3's `format('.2s')` formats axis tick labels (e.g., converting values to billions), and the `csv` function loads population data from a remote GitHub CSV file. The chart is interactive only through SVG `<title>` tooltips showing exact values.

Fork of Activity 7

This fork of Activity 7 displays a horizontal bar chart of population data for 30 countries in 2020. The visualization uses React to render an SVG with D3.js scales and axes. The code employs `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis, with data loaded via `d3.csv` from a GitHub repository. Each bar is a `<rect>` element with a `<title>` tooltip showing the population value, formatted using D3's `format` function to abbreviate large numbers.

This example shows a horizontal bar chart ranking 30 countries by their 2020 population, with each bar labeled with its country name and a tooltip displaying the formatted population value on hover. The visualization uses React components to render SVG elements, with d3.scaleBand and d3.scaleLinear handling the axes and data mapping. Data is loaded asynchronously via d3.csv from a GitHub-hosted CSV file, and axis ticks are formatted using d3.format to abbreviate large numbers (e.g., 'B' for billions). The chart features custom axis components that generate tick marks and labels, with styling applied through CSS selectors.

Fork of Activity 6

This example shows a horizontal bar chart of 2020 population estimates for 30 countries, using a React-based SVG rendering approach. The visualization ranks countries by population, with bars colored green and labeled axes showing country names and population values in billions. The code uses React components for layout, d3.js scaleBand and scaleLinear for positioning, and d3.csv to load the dataset from a GitHub-hosted CSV file. Tooltips provide formatted population values on hover, while the chart includes custom axis components and a Poppins font styling from Google Fonts.

Fork of Activity 7

This bar chart displays the 2020 population of 30 countries, sourced from a CSV file fetched via `d3.csv`. The visualization uses D3 scales (`scaleBand`, `scaleLinear`) and custom React components (`AxisBottom`, `AxisLeft`, `Marks`) to render the SVG. Horizontal bars are drawn as `<rect>` elements, with tooltip text showing formatted values using D3’s `format` function. The chart includes styled gridlines, axis labels, and a "POPULATION-2020" title, all rendered through React’s declarative component structure.

Fork of Activity 7

This visualization displays a horizontal bar chart of population data for 20 countries as of 2020, sourced from a GitHub-hosted CSV file. Using d3.scaleBand and d3.scaleLinear, the chart renders as an SVG, with blue tick lines for the y-axis and a population axis formatted with d3.format to abbreviate large numbers with 'B' for billions. Rectangles serve as marks, each with a tooltip showing the exact population value via an SVG title element. The visualization integrates D3 v5 with React, using hooks like useState and useEffect to load and manage data.

This is a horizontal bar chart showing the population of 20 countries in 2020, rendered as SVG elements within a React application. The chart uses D3 version 5 scales (`d3.scaleBand` and `d3.scaleLinear`) to map country names and population values to positions and lengths. Data is loaded from a CSV file via a custom `useData` hook, with tick marks styled blue and a green fill for each bar. Tooltips display the formatted population value on hover.

Fork of Activity 7

This example visualizes population data for 20 countries in 2020 using horizontal bars, with country names on the y-axis and population values on the x-axis, formatted in billions. The visualization reads data from a CSV file via D3’s `csv` function, applies a `scaleBand` for country categories, and a `scaleLinear` for population values. React components render SVG elements, with `AxisBottom` and `AxisLeft` generating ticks, and `Marks` producing rectangles with `<title>` tooltips. The code uses D3 v5 and React 16.9.
