This fork of the refactored bar chart example uses React with D3 v7 to render a horizontal bar chart of US city populations. The code defines reusable components for axes and marks, using `d3.scaleLinear` and `d3.scaleBand` to map population values and city names, while data is embedded and parsed via `d3.csvParse` from a local CSV string. Bars are drawn as SVG `rect` elements with hover opacity changes, and gridlines are created through a D3 axis call.

Fork of Fork of Refactored Bar chart with React & D3 -Rajan

The visualization displays US city population trends through two paired charts: a multi-series line chart comparing simulated population values for 2020, 2022, and 2024, and a combined bar-and-line chart showing 2020 bars with an overlaid growth-rate line. Built with React and D3 v7, it renders to a single responsive SVG using a viewBox. Data comes from a CSV file via `d3.csv`, with additional quantitative series generated through a seeded `mulberry32` random number generator. The implementation uses `d3.axisLeft` for grids, `d3.scaleLinear` for scaling, and a linear index-based x-axis.

Fork of refactoring bar chart with react and d3

This interactive bar chart displays population data for ten countries, sourced from a CSV file, using horizontal bars to encode each country's population value. Built with React and D3.js v7, the visualization renders entirely as SVG elements, with the `AxisBottom`, `AxisLeft`, and `Marks` components constructing the tick marks, axis labels, and rectangular bars. The chart uses D3's `scaleBand` for the categorical country axis and `scaleLinear` for the numeric population axis, while React's `useState` and `useEffect` hooks manage asynchronous data loading.

Fork of Stylised Bar chart

This horizontal bar chart displays populations for US cities, sorted in descending order with bars extending along a linear population scale. Built with React and D3 v7, it uses `d3.csv` to load data from a Gist-hosted CSV file and `d3.axisBottom` and `d3.axisLeft` for axes. The chart applies `scaleBand` for city categories and `scaleLinear` for population values, rendering bars as SVG `rect` elements with optional value labels via `d3.format`. A custom axis component adds faint vertical gridlines.

Fork of Stylised Bar chart

This horizontal bar chart displays the populations of major US cities in millions, using rectangles whose length encodes value and whose vertical position encodes city. Built with React and D3 v7, the visualization loads data from a remote CSV, applies a linear scale for the population axis and a band scale for the categorical city axis, and includes gridlines, axis labels, and hover opacity effects for readability.

Refactored Barchart_Fork of Axes with React & D3

This example demonstrates a horizontal bar chart displaying the population data of ten countries for the year 2020. The React-based visualization uses D3's `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis, with separate React components rendering the axes and marks as SVG elements. The data is loaded asynchronously from a remote CSV file using D3's `csv` utility, and the chart updates once the data is fetched.

Fork of bar chart with react and d3

This fork of a bar chart combines React and D3 to visualize population data for the top ten countries, loaded from a CSV file via a Gist URL. The SVG rendering uses D3's `scaleBand` for the categorical y-axis, `scaleLinear` for the numerical x-axis, and `max` to determine the domain. React manages the data state, displaying a "Loading..." message until the CSV is parsed. Both x-axis gridlines with tick labels and y-axis country labels are drawn using SVG elements within a transformed group.

Fork of Refactor Bar Chart woth React & D3

This visualization presents a horizontal bar chart of the ten most populous countries, sourced from the UN’s 2019 population dataset, using React to manage the component structure and D3’s `scaleBand` and `scaleLinear` to compute the layout. The code renders bars as raw SVG `<rect>` elements, with axes generated as SVG `<line>` and `<text>` elements via custom `AxisBottom` and `AxisLeft` components. Data loading is handled through a custom `useData` hook that fetches and parses the remote CSV file with D3’s `csv` function.

Fork of d3js

This example renders a horizontal bar chart of country populations using a React-free HTML page. It loads data from data.csv via `d3.csv`, then scales the values by 10 million. The visualization uses `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the y-axis, and `d3.axisLeft` and `d3.axisBottom` to draw the axes. Bars are appended as SVG `rect` elements within a grouped `<g>` transform, with height set by `yScale.bandwidth` and width proportional to population.
