This bar chart displays nine rectangular bars representing a dataset of numeric values, with varying heights corresponding to the data. It uses D3.js v4 to render the visualization as SVG elements within an HTML page. The chart generates bars by selecting all `rect` elements, binding the dataset, and appending new rectangles with the `.enter()` method. Each bar’s height and vertical position are calculated from the dataset values, while horizontal placement uses a `translate` transform. The bars are styled with a background color defined in CSS.

Learn D3.js

This bar chart visualizes a static dataset of nine numeric values using SVG rectangles. The example demonstrates how to construct a basic chart with the D3.js v4 library. The code sets the SVG canvas dimensions, calculates bar widths based on the data array length, and uses `d3.select` and `selectAll` to append `rect` elements. Each bar’s height and y-position are derived from the data values, with a `transform` attribute translating each rectangle horizontally. The chart is contained within an HTML page with a light background.

Learn Simple bar chart D3

This example uses D3.js v4 to render a simple bar chart of nine arbitrary numeric values. The chart displays each value as a vertical rectangle, with heights proportional to the data, rendered as SVG elements via `d3.selectAll("rect").data().enter().append()`. Bars are positioned using the `transform` attribute and translated horizontally based on their index. The chart is styled with a teal background from the accompanying CSS file. The dataset is hardcoded in JavaScript rather than loaded from an external source.

Learn D3.js

This example shows a simple bar chart built with D3.js v4, where each bar’s height corresponds to a value from a hardcoded JavaScript array of nine numbers. The chart is rendered as SVG inside an HTML page, with a title and a dedicated `<svg>` element. The code uses `d3.select` to set the SVG dimensions, `selectAll` with `data` and `enter` to create rectangles, and `attr` to position each bar via a `translate` transform based on its index. The bars are drawn from the bottom, using the SVG height minus the data value for the y-coordinate.

Bar Chart

This example shows a static bar chart of nine numeric values, with the bars displayed in an SVG container. The chart uses a fixed dataset defined in the code and renders the bars using SVG rectangles, which are appended to the SVG element created via `d3.select` and `append`. The visualization relies on D3.js version 7 for SVG generation, though the code does not include any axes, labels, or interactive behaviors—only the raw bars are drawn. The bars are positioned and sized based on the provided data values, but the implementation does not show scaling or styling details.

D3 tutorials

This example demonstrates a basic bar chart visualization. It shows a dataset of seven numeric values, each rendered as a fixed-width blue bar whose height corresponds to the value. The chart is built using D3.js methods to select the HTML body, append a `div` for each data point, and apply the CSS class `bar`. The bar heights are set inline using a JavaScript arrow function, and the initial styling is defined within a CSS style block. The code relies on `d3.select`, `d3.selectAll`, `.data`, `.enter`, `.append`, `.attr`, and `.style` to construct the visualization. The data is hardcoded as an array.

Bar Chart using D3.js

This visualization presents a simple bar chart of a fixed dataset representing eight numerical values, rendered as SVG rectangles using D3.js v4. The chart does not display axes or labels, relying instead on the raw bar lengths to convey magnitude against an implicit baseline. Using the `d3.select` and `selectAll` APIs, the code generates each bar’s height proportionally to its data value and applies a translate transform to position bars side by side with a fixed padding. The underlying data appears to be an arbitrary array rather than the UN population data referenced in the README, and the chart updates only on load with no interactive elements.

Intro to D3.js

This example shows a bar chart built with D3.js, displaying numeric values as vertical bars with corresponding value labels above each bar. It reads from an embedded dataset of eight numbers and renders them using SVG rectangles via `d3.select`, `selectAll`, and `data().enter().append()`. The chart sets fixed width and height attributes, calculates bar widths based on dataset length, and positions bars with a `translate` transform. Text elements display each value in a distinct color. The code uses the `d3.v5` library and is structured with React-ready starter files.

D3 Chart

This example shows a static bar chart built with React and D3.js v4, displaying a simple dataset of nine numeric values as vertical bars. The bars are rendered as SVG rectangles, with heights proportional to the data values and positioned horizontally using a translate transform. The code selects the pre-existing `<svg>` element with the class `bar-chart`, sets its dimensions, and appends rectangles via D3's data join (`enter()` and `append()`). The chart uses `d3.select` and `d3.min` APIs to map values to pixel coordinates.
