A simple bar chart displays the numeric values from a two-column CSV file, with each bar’s length proportional to the `y` value. The chart uses D3 v4’s `d3.scaleLinear` to map data to pixel widths, and appends `rect` and `text` elements within grouped `g` containers. Data is loaded via `d3.csv` and coerced to numbers using a custom `type` function. The bars are vertically stacked, with each row’s height fixed at 20 pixels, and the chart’s total height adjusts based on the number of data rows.

A bar chart displays six hardcoded numeric values as vertically scaled blue rectangles, with white strokes separating them. Each bar's height is proportional to the value divided by the maximum of the dataset, computed using `d3.max`. The chart renders in SVG via `d3.select` and `selection.append`, positioning bars with `attr('x')` based on their index and using a percentage-based height. The data is static, and the visualization uses d3.v4 without axes or labels.

A set of vertical bars displays a small numeric array, with bar heights proportional to values and fill colors interpolating from red to green based on each value’s position in the data range. The visualization uses d3.scaleLinear for the y-axis and color mapping, d3.scaleBand for horizontal positioning, and d3.schemeCategory20 as a fallback palette. Each rectangle is appended to an SVG canvas, with blue strokes outlining the bars. The code computes bar positions and heights directly from the scales, rendering the chart entirely with D3 v4.

A horizontal bar chart displays numerical values from a TSV file, with each bar labeled by its value. The chart uses D3.js version 3.5.5 to load the data, scale the bar widths linearly, and append SVG rectangles and text elements. The bars are rendered in an SVG container sized dynamically based on the data length, with heights fixed at 20 pixels minus a 1-pixel gap. Data values are coerced to numbers for scaling.

A simple bar chart displays five hardcoded values—10, 30, 15, 20, and 100—as vertical rectangles. The chart uses D3 v4’s selection and `append` API to create SVGs directly: `d3.select("body").append("svg")` builds the canvas, then `.selectAll("rect").data(data).enter()` generates bars whose height, y-position, and opacity are derived from each data value. Text labels repeat the same numbers below each bar using `d3.selectAll("text")`, with fixed styling for font size and monospace family. All geometry and styling are set via SVG attributes and styles, with no axes or gridlines present.

This example shows a simple bar chart with five vertical bars of varying heights. The bars are positioned side-by-side and share a consistent width. The chart uses D3 v4 with SVG rendering, and the data is a hardcoded array of numeric values. It binds the data to pre-existing `rect` elements using `selectAll('rect')` and sets their position, size, and fill color. The chart's height and bar widths are fixed constants, and stroke is applied for clear separation between bars. The code relies on D3’s selection API to directly update attributes without creating new elements.

A horizontal bar chart displays the number of cases by resolution type, using d3.scaleBand for the categorical y-axis and d3.scaleLinear for the numeric x-axis. Rectangles represent each value, with a custom tooltip showing the category and amount on mouseover. Data loads from a CSV file via d3.csv, and axes are drawn with d3.axisBottom and d3.axisLeft under d3.v4.

Five vertical red bars form a simple bar chart, with bar heights matching the numeric values in a hardcoded JavaScript array. The bars are drawn as SVG rectangles using D3 v4, with the `d3.selectAll('rect')` data join positioning each rectangle via `x` and `y` attributes based on its index and value. Each bar has a fixed width of 100 pixels, a black stroke, and fills the available height up to a maximum of 300 pixels.

Five vertical bars form a simple bar chart, with a single red bar highlighted among blue ones. The chart encodes an array of five numeric values as bar heights, with each bar positioned along the x-axis. The visualization is built with D3.v4 and rendered as SVG, using `d3.selectAll('rect')` to bind data to existing rectangle elements. The code then sets each rectangle’s x, y, width, height, fill, and stroke attributes, where the y-coordinate is calculated as the container height minus the data value.
