A horizontal bar chart displays the top 30 countries by 2020 population, sourced from an Activity6_Population.csv file. Steel-blue bars, rendered with SVG rect elements, list countries along the y-axis and population values along the x-axis. The chart uses D3 v7’s `selectAll` and `join` pattern to create bars and labels, with `d3.scaleBand` for the categorical axis and `d3.scaleLinear` for the numeric range.

Activity 6_Task 1

A horizontal bar chart displays 2020 population estimates for the top 30 countries from a CSV dataset. It shows population values as steelblue bars with formatted labels, using a linear scale for the x-axis and a band scale for countries on the y-axis. Built with D3 v7 and rendered as SVG, the code uses `d3.csv`, `scaleLinear`, `scaleBand`, `d3.axisBottom`, and `d3.axisLeft`.

A horizontal bar chart displays the population of the top 30 countries in 2020, with steelblue bars labeled with their values. Using d3.v7, the code loads CSV data via `d3.csv`, sorts it, and renders SVG with `d3.scaleLinear` for the x-axis and `d3.scaleBand` for the y-axis. Axes are drawn with `d3.axisBottom` and `d3.axisLeft`, while custom Mark components append rectangles and text labels, formatting numbers with `d3.format`.

Activity 6_Taskl 1

A horizontal bar chart displays the top 30 countries by population in 2020, using light green bars ordered alphabetically by country name. The visualization employs D3.js v7 with SVG rendering, using `d3.scaleLinear` and `d3.scaleBand` for positioning, along with `d3.axisBottom` and `d3.axisLeft` for axes. Population values are formatted as billions on the x-axis, while the data originates from a CSV file hosted on GitHub, fetched asynchronously via `d3.csv`.

Activity 6_Task 1

A horizontal bar chart displays population estimates for the top 30 countries in 2020, using d3.csv to load a CSV dataset and d3.scaleBand and d3.scaleLinear to map country names and population values. The SVG rendering uses d3.axisBottom and d3.axisLeft for tick marks, and the Marks module appends filled rectangles with steelblue to represent each bar’s length. Axis labels and a title for “POPULATION – 2020” are included.

This bar chart displays the populations of the top 30 countries in the year 2020, sourced from the included Activity6_Population.csv dataset. Each bar is rendered using SVG rectangles, with the country’s population value labeled directly at the end of each bar. The visualization is built with D3 v7, utilizing the `d3.scaleLinear` and `d3.scaleBand` scales to map data, while axes are created via `d3.axisBottom` and `d3.axisLeft`. The chart is presented with a clean layout, using a steelblue fill for the bars against a white background.

Activity 6_Task 1

This horizontal bar chart displays the 2020 population estimates for the top 30 countries, using a linear scale for population values and a band scale for country names. The visualization renders light green bars via SVG rectangles, with axes labeled "POPULATION-2020" and "Countries." It loads data from a CSV file using d3.csv, formats axis tick labels with d3.format to abbreviate values like millions and billions, and builds the chart using modular functions for axes and marks in d3.v7.

Activity6_Q 1.2

A horizontal bar chart displays the 20 most populous countries in 2010, sorted in descending order, using steelblue bars. The chart is rendered as an SVG with D3 v7, employing `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the categorical y-axis, and `d3.axisBottom` and `d3.axisLeft` for tick marks. Population data is loaded from a remote CSV file via `d3.csv`.

TASK-1(ACTIVITY-6)

This horizontal bar chart visualizes the top 30 countries by population in 2020. The D3.js v7 code loads CSV data from a GitHub Gist, converts the '2020' column to numerical values, sorts the data in descending order, and selects the first 30 entries. Using `d3.scaleLinear` for the x-axis and `d3.scaleBand` for the y-axis, it renders steelblue rectangles within an SVG, with hover states turning them orange. The visualization also includes a left y-axis, a bottom x-axis with compact tick labels, and text annotations showing each population value.
