This example shows a simple bar chart comparing the frequency of five Romance languages, loaded from a tab-separated file. The chart uses an SVG rendering approach with d3.v4, employing `d3.scaleBand` for the categorical x-axis and `d3.scaleLinear` for the numeric y-axis. Bars are drawn as `rect` elements with hover effects, and axes are generated via `d3.axisBottom` and `d3.axisLeft`, with the y-axis formatted as percentages. The code applies a custom data conversion function to parse frequencies as numbers before binding them to the visualization.

Create a Bar Chart

This example shows a simple bar chart depicting the frequency of five Romance languages (Spanish, Portuguese, French, Italian, and Romanian) using data loaded from a tab-separated values file. The chart renders as an SVG, with bars colored purple that darken to a reddish hue on hover. It uses D3 v4’s `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis, along with `d3.axisBottom` and `d3.axisLeft` to display labels and percentage ticks. The y-axis is annotated with the title “Frequency.”

Create a Bar Chart

This bar chart displays the relative frequency of five Romance languages—Spanish, Portuguese, French, Italian, and Romanian—using vertical bars. The visualization is built with D3 v4 and rendered as SVG, with data loaded from a tab-separated file. It uses `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.axisBottom` and `d3.axisLeft` for tick marks. Bars are colored with `fill`, highlighting Italian and French in black, while others appear in a muted orange. Hovering changes the bar color via CSS.

Create a Bar Chart

This bar chart displays the relative frequencies of five Romance languages—Spanish, Portuguese, French, Italian, and Romanian—using a simple SVG bar layout. The chart highlights Italian with a distinct green fill, while all other bars remain blue, and hovering over any bar changes its color to dark red. The visualization is built with D3 v4, using `d3.scaleBand` for the categorical x-axis, `d3.scaleLinear` for the numeric y-axis, and `d3.axisBottom` and `d3.axisLeft` for ticks. Data is loaded from a TSV file and parsed with a custom type conversion function that converts frequency values to numbers.

Create a Bar Chart

This bar chart displays the relative frequency of five Romance languages—Spanish, Portuguese, French, Italian, and Romanian—using data from a tab-separated values file. Blue bars render with SVG rectangles, while hover effects change their fill to a darker red. The chart uses d3.scaleBand for the categorical x-axis and d3.scaleLinear for the y-axis, which is formatted as percentages. Axes are generated with d3.axisBottom and d3.axisLeft, and the data is loaded asynchronously via d3.tsv.

Create a Bar Chart

This bar chart displays the relative frequency of five spoken languages, with Italian highlighted in green. The visualization loads data from a tab-separated file using `d3.tsv` and renders it as SVG rectangles. It uses `d3.scaleBand` for the x-axis categories, `d3.scaleLinear` for the y-axis frequencies, and `d3.axisBottom` and `d3.axisLeft` for tick marks. Hover effects change bar color, and the y-axis labels are formatted as percentages with ten ticks.

Create a Bar Chart

This example shows a bar chart of language frequencies, with bars colored blue by default and highlighted in green for French and Italian. The chart is rendered as SVG using D3 v4, with an x-axis for language names and a y-axis for frequency percentages. The code loads tab-separated data from `languages.tsv` using `d3.tsv`, scales the data with `d3.scaleBand` and `d3.scaleLinear`, and draws rectangles via `g.selectAll(".bar").enter().append("rect")`. Hovering a bar turns it dark red, as defined by the `.bar:hover` CSS rule.

Bar Chart in D3 v5

This bar chart shows the frequency of each letter in the English language, using a TSV file parsed with d3-dsv and rendered as SVG rectangles. The x-axis uses d3.scaleBand for letter categories, while the y-axis uses d3.scaleLinear with percentage formatting via d3-format. Hovering a bar changes its fill to brown, and axes are generated with d3-axis. Data loading is handled asynchronously through d3.tsv, with values converted to numbers using d3-array.
