This example shows population data for 20 countries as a horizontal bar chart. The bars’ lengths encode each country’s population value, with country names on the y-axis and a bottom axis formatted in billions. Built with React and D3 v5, it uses `scaleBand` for the y-axis, `scaleLinear` for the x-axis, and SVG `rect` elements. The CSV data is loaded via `d3.csv`, and tooltips display the formatted population using the D3 `format` API.

Question1(2)

This horizontal bar chart shows population figures for 20 countries in 2010, with each bar’s length representing the population value and country names listed on the vertical axis. The visualization uses React components to render SVG elements, with d3.scaleBand for the categorical y-axis and d3.scaleLinear for the numeric x-axis. Population values are formatted using d3’s format function, converting units to billions with the letter B. Data comes from a CSV file loaded via d3.csv, and hover tooltips display the exact formatted population using SVG title elements.

Question 1

This example shows the populations of ten countries in the year 2000 as a horizontal bar chart, with country names on the y-axis and population values on the x-axis formatted in billions. Built with React and D3 v5, it uses `d3.scaleBand` and `d3.scaleLinear` to position rectangular marks, and renders axes via custom SVG components. Data is loaded asynchronously from a CSV file using `d3.csv` and truncated to the first ten rows.

question1.2

This example displays a horizontal bar chart of population data for 20 countries in 2010. The visualization uses React with D3 v5 scale functions, specifically `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis. The bars are rendered as SVG rectangles, with axes created through custom components that map D3 scales to JSX elements. The chart loads CSV data from a GitHub gist, formats population values using the D3 `format` function, and includes a tooltip showing the formatted value for each bar.

Question1 part2

This example displays a horizontal bar chart of population data for twenty countries in 2010, sourced from a CSV file. It uses React with D3.js scales and axes, using `d3.scaleBand` and `d3.scaleLinear` with SVG for rendering. Bars are drawn as `rect` elements with a tooltip via the `<title>` element, and the axis tick labels are formatted using `d3.format`. The code demonstrates importing both D3 and local ES6 modules.

Question_1(b)

This visualization shows the population of 20 countries in the year 2010 as a horizontal bar chart. The bars are rendered as SVG rectangles using React components, with the x-axis scaled linearly and the y-axis using a band scale for country names. The code uses D3 v5’s `scaleBand`, `scaleLinear`, `max`, and `format` for axes and tick labels, while the dataset is loaded via `d3.csv` from a GitHub URL. A simple tooltip is provided through SVG `<title>` elements showing the formatted population value.

Question1.2

This example shows a horizontal bar chart depicting the populations of twenty countries in 2010. Built with React and SVG, it uses D3 v5's `scaleBand` for the categorical y-axis and `scaleLinear` for the population x-axis. The `csv` function loads data from a GitHub-hosted file, and custom `AxisBottom` and `AxisLeft` components render the axes with formatted tick labels. Each bar is a `rect` generated by the `Marks` component, with a `<title>` element for tooltip values.

Question-1.2 Task-1

This horizontal bar chart displays the population of 20 countries in 2010, sorted by country name. The visualization uses React with D3.js scales and axes to render SVG rectangles, with bars sized proportionally to population values. The code imports D3’s `scaleBand`, `scaleLinear`, and `format` APIs, while loading data via `csv` from a GitHub-hosted CSV file. Tooltips show formatted population values using a custom tick format that shortens large numbers to billions.

Question1.2

A horizontal bar chart displays the top 20 countries by 2010 population, using a CSV dataset loaded via D3's `csv` function. The chart is rendered as SVG with React components, mapping country names to a `scaleBand` y-axis and population values to a `scaleLinear` x-axis. Data values are formatted with D3's `format` function, converting values into billions with a 'B' suffix. Hovering over each rectangular bar reveals a tooltip with the population value, while blue tick lines and green bars provide clear visual separation.
