This histogram displays the distribution of a numeric variable (price) from a CSV dataset loaded from a GitHub repository. The visualization uses D3.js v7 with an SVG rendering approach, where the `d3.histogram()` API computes the binning and thresholds, and axis scales are created with `d3.scaleLinear()`. Bars are appended as SVG rectangles, and the chart is responsive, redrawing on window resize with a debounce function. The design uses a dark background with steelblue bars.

Histogram

Definition

A histogram is an accurate graphical representation of the distribution of a numeric variable. It takes as input numeric variables only. The variable is cut into several bins, and the number of observation per bin is represented by the height of the bar.

What For

Histogram are used to study the distribution of one or a few variables. Checking the distribution of your variables one by one is probably the first task you should do when you get a new dataset. It delivers a good quantity of information.

Steps:

  1. A histogram displays the distribution of a numeric variable. So you basically need only one column in your input file.
  2. This numeric variable is provided to the d3.histogram() function that will compute the binning and returns the coordinates of each bar.
  3. These bars can thus be drawn using a classic .append("rect") approach.

Fork of Histogram

This interactive histogram visualizes the distribution of price data from a CSV file hosted on GitHub. The chart is rendered as SVG and automatically resizes with the browser window. The code uses `d3.histogram()` to bin the numeric values, `d3.scaleLinear()` for the x and y axes, and `d3.csv()` to load the dataset. Bars are drawn with SVG `rect` elements, colored steelblue, with a debounced resize handler that rebuilds the visualization on window changes.

Histogram

This interactive histogram visualizes the distribution of one numeric variable using data loaded from a CSV file. Built with D3 v7, it renders bars as SVG rectangles, with the x-axis scaled linearly and the y-axis representing bin counts. The chart updates responsively on window resize, recalculating the histogram with 40 thresholds to accommodate the new width. Data is fetched from the `data_to_viz` GitHub repository.

Fork of Histogram

This example shows a histogram of wine prices from a CSV dataset, using bars to display the distribution of the numeric price variable across 40 bins. The visualization updates responsively when the window is resized. The code uses d3.histogram() to compute binning, d3.scaleLinear() for both axes, and d3.axisBottom() and d3.axisLeft() for tick marks. SVG rectangles are appended and transformed to represent each bin, with a debounced resize listener triggering redraws of the histogram.

This example presents a histogram of the `price` values from a single-column CSV dataset. Built with React and D3 v4, it creates an SVG visualization with a linear x-axis and automatically binned y-axis counts. The code explicitly uses `d3.scaleLinear`, `d3.histogram`, and `d3.axisBottom`/`d3.axisLeft` to render the distribution, with bars filled in olive. Data is fetched from a remote GitHub-hosted CSV using `d3.csv`, and the histogram bins are defined by the domain and 19 ticks.

This interactive histogram displays the distribution of a single numeric variable (price) from a CSV dataset loaded from GitHub. Users adjust the number of bins via a numeric input, triggering a smooth animated transition of the bars. The visualization uses D3.js v5 with `d3.histogram`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` to compute bin counts and render SVG rectangles. The `transition().duration(1000)` API animates updates to the y-axis and bars, while enter/exit transitions add or remove rectangles as bin count changes.

Histogram

This histogram visualizes the distribution of horsepower values from a CSV dataset, with counts binned across a linear scale. The chart uses D3 v6 to implement the visualization, employing `d3.histogram()` to generate bins and `d3.scaleLinear` for both axes. Each bar is rendered as an SVG `rect`, and interactive tooltips appear on hover, displaying the bin’s range. The chart includes a titled SVG output and left-aligned axis labels, with bars filled in a solid blue color.

This interactive histogram displays the distribution of a single numeric variable from a CSV dataset of prices. A slider dynamically adjusts the number of bins from 1 to 100, with smooth 1000ms transitions updating both the bar widths and the y-axis scale. The visualization uses d3.histogram to compute bin values, d3.scaleLinear for axes, and d3.axisBottom/axisLeft for rendering scales. Bars are drawn as SVG rectangles with a teal fill, while d3’s data join pattern handles entering and exiting elements during updates.

Histogram

This histogram visualizes the distribution of a numeric variable, grouping observed values into discrete bins and displaying their frequencies as vertical bars. It uses the D3.js library, specifically leveraging `d3.histogram` and `d3.scale` APIs to compute bin ranges and map data to screen coordinates. The rendering relies on SVG paths generated from the binned counts, with axes and labels drawn via D3’s measurement and tick utilities. The dataset originates from a GitHub gist, and the code operates entirely in the browser without external data files.
