This interactive bar chart displays the 2020 population figures for 30 countries, using horizontal bars to rank each nation along a linear scale. The visualization employs React to manage the SVG rendering, with D3 v5 handling data loading, scales, and axis generation through functions like `scaleBand` and `scaleLinear`. Population data is fetched from a CSV file and formatted using D3's `format` utility, converting values to billions for tooltips. The chart features blue tick lines, green bars, and a Poppins font, with the y-axis listing country names and the x-axis labeled “POPULATION-2020.”

This bar chart displays the 2020 populations of 30 countries, sorted along a vertical categorical axis. The visualization uses D3 v5 scales to map population values to horizontal bar lengths and country names to vertical bands. The React-based SVG rendering includes custom axis components that generate tick marks and labels, with a green fill for each bar. Population data is loaded from a remote CSV file, and a tooltip showing formatted population values appears when hovering over each bar.

This horizontal bar chart displays the 2020 population estimates for 30 countries, with bars sorted by country name along the y-axis and population values on the x-axis. The visualization uses React components to render SVG elements, with D3’s scaleBand and scaleLinear handling the spatial mapping and d3.csv loading population data from a GitHub-hosted CSV file. Axis components generate tick marks and labels, while a formatter converts large numbers into abbreviated values like “1.2B” for readability.

This bar chart visualizes the 2020 population of 30 countries, using a horizontal layout with bars scaled by population. The visualization is built with React and D3 v5, leveraging `d3.scaleBand` and `d3.scaleLinear` for axes and `d3.format` for tick labels (e.g., converting "G" to "B"). Data is loaded from a CSV URL via `d3.csv` and rendered as SVG rectangles with tooltips. A Poppins font and CSS styles control the visual presentation.

This bar chart displays the population of 30 countries for the year 2020, ranked along the vertical axis. The chart uses a green horizontal bar for each country, with a tooltip showing the precise population value on hover. It loads data from a CSV file via D3's `csv` function, and constructs a band scale and linear scale for the axes. The React components render SVG elements for the axes and marks, while D3's `format` function converts large numbers into abbreviated strings.

Activity6_Task1

A horizontal bar chart displays the populations of 30 countries in 2020, sorted by country name with colored green bars. Built with React and D3 v5, it uses `scaleBand` for the y-axis and `scaleLinear` for the x-axis, with SVG rectangles rendered via the `Marks` component. Population values are loaded from a remote CSV file using `d3.csv`, converted to numbers, and formatted with `d3.format` to abbreviate large numbers (e.g., "1.5B"). Axis labels and ticks are generated by custom `AxisBottom` and `AxisLeft` components, and hovering reveals exact values via SVG `<title>` tooltips.

This bar chart displays the population of 30 countries in 2020, sorted by country name along the vertical axis. The chart uses React with D3 v5 to render SVG elements, employing `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis. Population values are formatted using D3’s `format` function, converting billions to a readable label. The data is loaded via `d3.csv` from a remote GitHub source, and each bar includes a tooltip showing the formatted population value.

This bar chart displays the 2020 population of 30 countries, with countries listed on the vertical axis and population values represented by horizontal bar lengths. The visualization is built using React with D3 v5 for data loading and scales, rendering to SVG. The code uses `scaleBand` for the categorical y-axis, `scaleLinear` for the quantitative x-axis, and `format` for abbreviating population labels (e.g., converting billions to "B"). Data comes from a remote CSV file via `d3.csv`, with population values multiplied by 1000 during parsing.
