This example shows a horizontal bar chart of the top 30 countries by 2020 population, with the y-axis listing country names and the x-axis displaying population values in billions. Built with React and D3 v5, it uses `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis, rendering SVG rectangles via the `Marks` component. The data is loaded asynchronously from a CSV file using `d3.csv`, and axis ticks are generated with `xScale.ticks()`, formatted with the `d3.format` SI prefix to abbreviate large numbers.

This example shows a horizontal bar chart of the top 30 countries by 2020 population, with each bar labeled by country name and values formatted in billions. The visualization uses React with D3 v5 scales (scaleBand for the y-axis and scaleLinear for the x-axis), rendering SVG rectangles via the Marks component. Data is loaded as CSV from a GitHub repository and processed with d3.csv, with population values multiplied by 1000. The chart includes axis components for bottom and left ticks, plus an "POPULATION-2020" axis label.

This example displays a horizontal bar chart of the top 30 countries by 2020 population, using SVG rectangles scaled by a linear population axis and a categorical country axis. The visualization loads data from a CSV file and formats population values in billions with D3's `scaleLinear`, `scaleBand`, and `format` utilities. React components render the axes and marks, with tooltips provided by SVG titles and blue axis ticks styled via CSS. The chart highlights D3 v5 integration within a React framework, demonstrating basic data loading and declarative chart construction.

ACTIVITY 6_Task 1

This horizontal bar chart displays the top 30 countries by population in 2020, ranked along the y-axis with bar lengths representing the population values. The visualization is built with D3 v5 and React, using SVG rendering. The `scaleBand` and `scaleLinear` functions map the categorical country names and numeric population values, while custom `AxisBottom`, `AxisLeft`, and `Marks` components handle ticks and rectangular bars. Data is loaded asynchronously from a remote CSV file via D3’s `csv` function, with population values formatted using the `format` utility.

Activity6_Task 1

This bar chart displays the top 30 countries by 2020 population, ranked along a vertical band scale. The visualization uses D3 v5 for data loading and scale creation, with React components rendering SVG rectangles for each bar. The code applies `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis, formatting tick labels with `d3.format`. Data is fetched as CSV from a GitHub repository, with values multiplied by 1000 to represent actual population figures.

activity 6_Task 1

A horizontal bar chart displays population figures for the top 30 countries in 2020, using a linear scale for population and a band scale for country names. The visualization, built with React and D3 v5, renders SVG rectangles whose lengths encode population values, with axes and tick labels generated by custom components. Data is loaded from a CSV file via D3's `csv` function, and the axis formatting converts large numbers to abbreviated labels.

Activity 6_Task1

This example shows a horizontal bar chart of the 30 most populous countries from a 2020 dataset, using population values displayed on the x-axis and country names on the y-axis. The React-based visualization uses D3 v5’s `scaleBand` and `scaleLinear` for positioning, with bars rendered as SVG `<rect>` elements via the `Marks` component. Data is loaded asynchronously from a CSV using `d3.csv`, with axes generated by `AxisBottom` and `AxisLeft` components. The chart includes formatted tick labels (e.g., converting billions) and a title, with green bars styled via CSS.

Activity 6 task1

This example displays a horizontal bar chart of the top 30 countries by 2020 population, using a green fill for each bar. The chart is built with React and rendered as an SVG, using D3’s `scaleBand` and `scaleLinear` to map country names and population values to the axis positions. The data is loaded from a remote CSV file using D3’s `csv` function, with population values multiplied by 1000, and includes axis components built with `AxisBottom` and `AxisLeft` to provide tick labels and grid lines.
