This example shows a bar chart of 20 numeric values, with each bar colored on a green scale and its value labeled directly on top. The data is a fixed array of numbers embedded in the code. Using D3.js version 3, the chart is rendered as an SVG, with `d3.select` to append the SVG element and chained `.enter()` calls to create `rect` and `text` elements. Bar heights and colors derive from each value, while labels are centered using the `text-anchor` attribute.

Visualization Implementation 2 (VI2)

##Tableau

##1) Bar chart of passing yards per player,with conference mapped to color T image

Players are grouped by conference

##2)Scatterplot of 2 interesting variables, with conference mapped to color T image

Scatterplot of rushing touch down vs.passing touch down to observe the correlation between the between the attributes.

##3)One other interesting graph that uses a derived variable T image

Scatterplot for average rushing attempts vs. passing attempts.Details are visualized for school and conference.

##Insight gained from each of the 3 Tableau chart

1.Visualization of passing yards per player grouped by conference

2.Correlation of Passing and Rushing touch down statistics.

3.Average of passing attempts and average of rushing attempts of players of a school in a conference.

##Comments on Tableau

1.It provide a easy-to-use drag and drop interface that can help you quickly turn your data into business insights.

2.Tableau connects easily to nearly any data source, be it corporate Data Warehouse, Microsoft Excel or web-based data and allows instantaneous insight by transforming data into visually appealing and interactive visualisations.

##Working through the D3 tutorial

1.Translating data ino color by using rgb().

2.Using SVG to add SVG elements such as text,allignment,draw shapes.

3.There is a learning curve to javascript.

D3: Drawing a Bar Chart

This example demonstrates a basic bar chart built with D3 v7 in an SVG container, visualizing an array of 20 numeric values. The bars grow downward from the top of a 500×100 pixel canvas, with each bar’s height proportional to its data value multiplied by 4, and its fill color transitioning from dark to lighter blue based on the data. The chart also overlays each bar with white, 11px sans-serif text labels showing the exact data values, centered horizontally within each bar. The code uses `d3.select` to append SVG elements and the data-join pattern with `.enter()` to create rectangles and text nodes.

Bar Chart I

This bar chart visualizes six numeric values—4, 8, 15, 16, 23, and 42—as horizontal bars whose widths are proportional to the data. The chart uses D3 v3’s `d3.scale.linear` to map the domain from zero to the maximum value (42) onto a pixel range of 0–420. Each bar is a styled `div` element with a steelblue background, white text, and a width set via the `style` operator. The code appends these divs using `d3.select` and `.selectAll("div").data(...)`, with the data bound to the DOM. The bars’ labels display the original values.

Bar Chart I

A basic bar chart visualizes a small fixed dataset of six numeric values, with each bar’s length and label representing its value. The chart uses green horizontal bars with white text, positioned through inline styles. This example, from the “Let’s Make a Bar Chart” tutorial, is built with D3 v3 and an HTML `<div>` per bar instead of SVG. The code employs the `d3.scale.linear` API to map data values to pixel widths, and uses D3’s selection and data-joining methods to create the bars.

CS 725 Information Visualization - VI2

This example demonstrates a bar chart for a dataset of 20 numeric values, with each bar’s height and color intensity proportional to its value. The chart is rendered as an SVG using D3.js (version 3.5.5), where `d3.select` appends an SVG element, and `selectAll("rect")` with `data()` and `enter()` creates the bars. Text labels are positioned at each bar’s top using an inverted coordinate system, where `y` is calculated from the height. The source code is a standalone HTML file, and the dataset is hardcoded as an array. The rendering uses basic D3 APIs such as `attr` for styling and `text-anchor` for label alignment.

bar chart examples

This example shows a simple bar chart of ten values from an inline array, with bars colored blue except for the single bar at 250, which is red, and a y-axis with blue tick labels except the 250 tick in red. The chart is rendered as SVG via D3 v5, using a linear scale for the y-axis and manually positioning each rectangle with fixed width and spacing. The code explicitly sets bar height as the difference between the chart height and the scaled value, and the axis is drawn with `d3.axisLeft`. The data is hardcoded, and the visualization demonstrates basic scaling, axis generation, and per-bar styling without interactive features.

D3: SVG bar chart with value labels (centered)

This example renders a static SVG bar chart from an inline array of 20 numeric values, with each bar’s value displayed as white, centered text labels at its top. The visualization uses D3 v7’s data join (`selectAll`, `data`, `enter`) to append SVG `rect` elements and corresponding `text` elements, with bar heights and fill intensities scaled to the data. Bar spacing and label positioning are computed arithmetically from the chart width and dataset length, while text anchoring is handled via the `text-anchor` attribute.

D3: Basic Barchart

This example shows a basic bar chart of 20 numeric values rendered as SVG rectangles, with each bar labeled by its value in white text. The chart uses D3 v5 scales, including a `scaleBand` for the x-axis positioning and a `scaleLinear` for the y-axis height calculation. Data is bound via `selectAll("rect").data()`, with bars and text labels positioned using the scales. The code loads D3 from UNPKG and demonstrates simple SVG generation without axes or interactivity.

Bar Chart

This bar chart displays six numeric values as horizontal rectangles, with each bar’s length scaled linearly from its minimum to maximum value. The visualization uses D3 v7 to bind the data array to SVG groups, appending a rectangle and a text label per value. The chart positions each row using transform translations, and the x-axis scaling is handled by d3.scaleLinear. The SVG dimensions are fixed at 500 pixels wide with a bar height of 20 pixels, and the chart is rendered directly into the body element.
