This D3 v4 bar chart demonstrates interactive data-binding by rendering an SVG with rectangles sized from a hardcoded array of numbers. The chart uses `d3.scaleLinear` for the y-axis and `d3.scaleBand` for the x-axis, with bars turning red on mouse hover and green on click, while retaining the green color after the click via a custom `__clicked` property. The example, forked from romsson's block, differs from its non-binding predecessor by applying D3's `selectAll` and `.data()` method to attach data to shapes, enabling direct event handlers that reference each data value.

D3 bar chart with data-binding

This example demonstrates a simple D3 bar chart that binds an array of numeric values to SVG rectangles, with each bar’s height proportional to its data point. It uses D3 v4’s `scaleLinear` to map the data domain to a fixed pixel range, then applies the `data()` and `enter()` methods to create and position the rectangles. The chart renders with a minimal style—unfilled bars with black outlines—and the data is hardcoded as a static array. The code relies on standard D3 selection and scale APIs, with the SVG container set to 960 by 500 pixels.

D3 DataBinding

This example demonstrates a simple bar chart that binds JSON data to SVG elements, showing municipal census values as horizontally sorted bars. The visualization uses D3.js v5 to load data from a GitHub-hosted JSON file and renders two separate SVG containers, though only the first is populated. The code employs D3’s data join pattern with `selectAll`, `data`, and `enter` to append rectangles for bars and text labels for municipality names. A linear scale maps the data domain to pixel widths, while bar heights are fixed and y-positions are computed by index. The chart sorts data in descending order by census value before rendering.

D3 bar chart without data-binding

A static SVG bar chart displays twenty purple rectangles of varying heights, representing an inline array of numeric values. The code uses D3 v4 scales, `d3.scaleLinear`, to map data values to pixel heights and positions, though it does not use the data join's update or exit selections. Bars are appended via `selectAll("rect").data(data).enter()`, with each rectangle’s height and y-coordinate computed from the scale; the x-position is calculated manually from the index. No interaction or animation is present, and the chart is rendered with fixed SVG dimensions.

D3: An SVG element tooltip

This example shows a bar chart built from a hardcoded array of numbers, with an SVG text tooltip that appears on mouseover to display each bar’s value. The tooltip is appended directly to the SVG and removed on mouseout. Clicking a bar sorts the rectangles in ascending or descending order using a staggered transition. The code uses D3 v4 with `scaleBand`, `scaleLinear`, and `transition` for sorting, while CSS `rect:hover` styling changes the fill to orange.

D3 DataBinding

This example shows a simple bar chart built with D3 v5, displaying census data for municipalities from a JSON dataset. The visualization renders two SVG elements, though only the first is populated with data. The code uses `d3.scaleLinear` to map census values to bar widths and `d3.ascending`/`d3.descending` for sorting. It demonstrates data binding with `selectAll` and `enter().append()` to create rectangles and text labels, though the label positioning is incomplete. The data is loaded via `d3.json` from a GitHub-hosted source.

D3 DataBinding

A simple bar chart visualizes municipal census data using two SVG elements, where each bar's width maps to a numeric census value via `d3.scaleLinear`. The code loads JSON data from a GitHub repository using `d3.json` and binds it to rectangles and text labels with `.data()` and `.enter()`. Bars are sorted in descending order and labeled with municipality names, while the chart dimensions derive from the SVG attributes. Built with D3 v5, the example demonstrates basic data joins for both shapes and annotations, though it only renders one of the two defined chart instances.

D3: Basic Barchart

This example shows a basic bar chart of 20 numeric values rendered as SVG rectangles, with each bar labeled by its value in white text. The chart uses D3 v5 scales, including a `scaleBand` for the x-axis positioning and a `scaleLinear` for the y-axis height calculation. Data is bound via `selectAll("rect").data()`, with bars and text labels positioned using the scales. The code loads D3 from UNPKG and demonstrates simple SVG generation without axes or interactivity.

svg & d3 - example

This example demonstrates a simple bar chart built with D3.js v4, using an SVG-based rendering approach. It displays a small dataset of four numeric values as horizontal bars, with a separate checklist interface above the chart that lists the same data points as labeled checkboxes. The visualization pairs categorical data with an interactive checklist, though the chart itself is static and does not respond to checkbox state. The code uses D3 selections and data binding (`d3.select`, `selectAll`, `data`, `enter`, `append`) to create both the label inputs and the bar elements, while CSS styles define the bar colors and text alignment. The chart is rendered as a series of `div` elements within a container, with widths proportional to the data values.
