Clicking the text above the chart removes the first value from a fixed array, shifting the dataset leftward. D3 v4 uses a band scale for the x-axis and a linear scale for the y-axis to render SVG rectangles and white text labels. The update pattern calls `selection.enter`, `merge`, and `exit` with chained `transition` methods, animating exiting bars and labels out the right edge while repositioning the remaining elements over 500 milliseconds.

D3: Removing values from a chart

A bar chart displays 20 numeric values, each labeled with its value. Clicking the text prompt removes the first data point and smoothly slides the remaining bars and labels left into their new positions. The example uses D3 v4’s `scaleBand` and `scaleLinear` for axes, and relies on selection `enter`, `merge`, and `exit` transitions to animate rectangles and text over 500 milliseconds. It binds data with a custom key function and renders entirely as SVG.

D3: Removing values from a chart

Clicking the text removes the first value from a static D3 bar chart, shifting the remaining bars left and recalculating their heights. The example demonstrates the enter, update, and exit pattern with `dataset.shift()`, re-binding data to SVG `rect` and `text` elements, and updating ordinal `xScale` and linear `yScale` domains. Transitions animate the bars sliding to new positions or exiting off the right edge.

D3: Removing values from a chart

Twenty vertical bars show a dataset of twenty values, rendered as an SVG bar chart with numeric labels. Clicking the text above the chart removes the first value from the array and updates the chart, using `d3.scaleBand` and `d3.scaleLinear` to recompute domains, `dataset.shift()`, and `transition()` with `duration(500)` to animate the remaining bars and labels into their new positions. The bars exiting the chart slide off the right edge before being removed.

D3: Adding and removing values from a chart (dynamic labels included)

This example shows a bar chart where clicking the “Add” or “Remove” text buttons appends or removes a data value, with bars and their numeric labels animating to updated positions. Built with D3 v4, it uses `d3.scaleBand` and `d3.scaleLinear` for axes, a key function on `d.key` for data binding, and `selection.merge` with `transition` to smoothly shift rectangles and text over 500 milliseconds. Entering elements slide in from the right, while exiting ones slide out left before being removed.

D3: Adding values and elements to a chart

A bar chart displays a fixed dataset of 20 values as blue rectangles with white value labels, using D3 v4 scales (`scaleBand` and `scaleLinear`) and SVG rendering. Clicking the text above the chart triggers a transition: a random number between 0 and 25 is appended to the data array, the scales’ domains are recalculated, and both bars and labels animate over one second via `transition()` and `merge()` to accommodate the new element with a slightly narrower band width.

D3: Adding values and elements to a chart

This example shows a bar chart that grows dynamically as users click a text prompt, adding a new randomly generated value between 0 and 25 to the existing dataset. Each bar is labeled with its corresponding value, rendered as white text directly on the bar. The chart uses D3 v4’s `scaleBand` for the x-axis and `scaleLinear` for the y-axis, with SVG `rect` and `text` elements. Clicking triggers D3’s `.transition()` API to animate the bars and labels, smoothly repositioning and resizing them as the domain and axes update.

D3: Adding values and elements to a chart

This example demonstrates an interactive bar chart that starts with 20 values and adds a randomly generated data point each time the user clicks the text prompt. The visualization shows a static bar chart with data labels, and the interactive element updates both the chart's scales and geometry. Built with D3 v4, it uses `d3.scaleBand` and `d3.scaleLinear` to manage axes, and `transition` to animate the repositioning and resizing of rectangles and text elements over 500 milliseconds. The data is an inline JavaScript array, rendered as SVG.
