This example displays a text prompt and computes summary statistics for a small dataset of U.S. states and their populations. It uses D3 v4’s `d3.mean` and `d3.sum` array methods to calculate the average population, then repeats the calculation manually with a `while` loop. The SVG text element serves as a placeholder, while the results are printed to the browser console. The code relies on D3’s selection and array utilities, with no data loading or rendering beyond the static label.

This example displays a static SVG visualization of state population data, showing the mean population calculated from a small array of four U.S. states. The code first uses `d3.mean()` to compute and log the average, then replicates the calculation without the helper using `d3.sum()` and a manual `while` loop, printing each result to the console. The SVG canvas renders a placeholder text message, while the population computations are performed entirely in JavaScript using D3 v4 array methods. The visualization itself does not map the data graphically, focusing instead on demonstrating statistical calculations in the console.

This example presents two JavaScript practice problems embedded in a static HTML page, with no SVG or visual output. It shows a small array of four U.S. states and their populations, then asks the viewer to compute the mean population using the D3 v4 API’s `d3.mean()` method, and again without it. The code prints results to the browser’s developer console, and includes a minimal inline style for full-screen body margins. The data is hardcoded in the script, and the page uses only D3’s core utility function for the first calculation.

This example presents two JavaScript practice problems embedded in an HTML page. It shows how to compute the average population of a small array of U.S. states, first using the d3.mean() method and then manually using d3.sum() divided by the array length. The page prints results to the browser’s developer console rather than rendering any visual elements. The code relies on d3.v4 and defines state objects with name, id, and population data inline.

This example presents two JavaScript practice problems embedded in an HTML page with no SVG or visual output. The first problem uses the d3.mean() function from d3.v4 to calculate and log the average population of four U.S. states (Alaska, Virginia, Arizona, Florida) stored in a states array. The second problem asks the viewer to compute the same average without d3.mean(), relying instead on the browser’s developer console to observe results. The code uses the D3.js library for the mean calculation and plain JavaScript for array handling, with no rendering or data visualization involved.

This example demonstrates five JavaScript practice problems solved with array iteration and sorting methods, with results printed to the browser’s developer console rather than rendered visually. The code uses `forEach`, `search`, `every`, and `sort` to filter states by location, compare arrays, sort state objects alphabetically, and identify even population values. No SVG or D3 visualization is created; the page simply displays instructional text, and D3 v4 is loaded but not utilized in the shown logic.

This example demonstrates a minimal D3.js visualization: a blank SVG canvas with a single text element displaying a prompt to edit the code. The visualization uses the D3 v4 library to select the body element, append an SVG of 960 by 500 pixels, and render a sentence in a monospace font. The rendering is entirely SVG-based, and the code structure follows the blockbuilder.org template, with the source appearing to be a basic starting point for user modification.

This visualization shows the changing age distribution of the U.S. population over time, using a sliding time window controlled by arrow keys. The chart displays population counts for each birth year as horizontal bars, with the current year prominently labeled. Built with D3.js version 3, it loads data from a CSV file and uses scales, axes, and nested data structures. Rectangular bars and text labels are rendered as SVG elements, with smooth transitions animating the bars as the displayed year updates.

This example presents five JavaScript practice problems embedded in an HTML page, with instructions to view output in the developer console. The code uses d3.v4’s `d3.ascending` method to sort an array of state objects by name, and demonstrates array iteration with `forEach`, string searching with `includes`, and conditional logic to filter states by location or even population values. No SVG or visual rendering is involved; the focus is purely on console-based problem-solving with plain JavaScript arrays and objects.
