"Discover the power of D3.JS with three dazzling charts on a single page, plus a host of additional

As a student, I struggle with English and it makes me feel sorry and anxious...

Despite that, I want to create three scatter plot charts on the same page using a single data file (csv).

The dataset includes columns for Name, Height, Weight, and Grade (ranging from 0.0 to 5.0).

----------------- Check out Chart.Html -------------------------

          Chart1

----------------------------- [Height]

          Chart2

----------------------------- [Weight]

          Chart3

----------------------------- [Grade]

I have been studying d3.js and learning how to divide HTML file into three areas to display these charts.

Are there any other options available?

Another query I have is regarding the data sets:

Name, Height, Weight, Grade John, 180, 80, 4.5 Smith, 175,95, 3.2 Ryu, 187, 87, 4.0

When plotted, these three data points will represent as dots on the chart.

If a user clicks on a dot in Chart1 (let's say it represents Ryu, 187, 87, 4.0),

The color of the dot should change (by default it's red, but turns blue upon clicking) on all three charts: Chart1, Chart2, and Chart3.

Is this functionality achievable? If so, could you provide an example or useful documentation?

If you require additional clarification, please let me know as I am more than willing to provide further details.

:) Thank you for taking the time to read my inquiry.

Answer №1

Greetings Joony,

Are you interested in learning how to create a Scatter Plot? If so, I recommend checking out this helpful tutorial by Scott Murray: Scatter Plot - Scott Murray.

In order to load your data efficiently, you can utilize the d3.csv() function. For more details on this process, visit this link.

To begin creating your Scatter Plot chart, follow the instructions provided and ensure that all codes are enclosed within the d3.csv function.

If you plan on creating multiple charts, consider setting up separate div elements for each one. By using the same code structure for each scatter plot and simply adjusting the column names, you can easily generate multiple charts. Store the column names in variables after loading the data with d3.csv for added convenience.

Prior to getting started, I recommend reading "D3 Tips and Tricks" by Lean Pub, which is available as a free PDF for beginners.

d3.csv("path to the file.csv", function(data, error) {
    // Implement codes for your scatter plot
})

For further information on d3, you can explore the official documentation and examples at this link.
