Pull readers into your data story with a compelling introduction. Notice how this paragraph appears in a larger font than others, because the HTML code begins with a "lead" class.
A good introduction raises your guiding question, outlines key findings that answer it, and explains why it matters to both our community partner. Since you also need to provide essential background information for general readers, a typical introduction requires at least 2-3 paragraphs.
Compose your data story in your Google Doc, where it's easier to write and edit, especially when working with other people. When you're ready, create your own copy of this GitHub dataviz-story-template , and publish it online using Settings > Pages. When your version is published, copy and paste the live web link into your README file so you can easily find it.
In your GitHub copy of this template, open the "index.html" file to see how everything must be written in HTML format. Click the pencil symbol in GithHub to edit the file. HINT: In the upper-right corner, switch the dropdown menu from "No Wrap" to "Soft Wrap" to easily view long segments of code in your screen.
Paragraphs like this one must begin with a "p" tag and end with a "p" closing tag.
Links must begin and end with "a" anchor tags, with the web address inside either single or double quotes. If you need guidance, check out this W3Schools HTML Tutorial.
Change default navigation labels (such as "Section 1") to customized labels to guide your readers. While some authors use traditional headers (such as "Findings" or "Sources & Methods"), you're welcome to innovate with more creative headers (such as "Why It Matters" or "How We Made This"). Be sure to EDIT names in TWO locations in the template: the Navigation Container (around lines 30-50) and the corresponding Sections labels further below. EDIT only the reader-friendly labels, and do not change the underlying code.
TELL your story and SHOW your evidence. When describing charts, maps, or tables that appear further below, refer to them "...as shown in Figure 1" or "...as shown in Table 1" and include those figure/table numbers in the titles or captions below.
Embed each of your published visualizations as an HTML iframe code, following instructions in Chapter 9 of HODV, similar to the sample below.
EDIT CAPTIONS like this -- Figure 1: Explore the interactive chart AND ADD your description of the chart here. Make sure your caption includes a direct link to your published chart or map in case the embed code fails to display.
Create a separate section to describe how you obtained your data, key steps in your process, and cautions for interpreting its meaning. Write for an audience of future Trinity College students who may wish to replicate your steps. Write in HTML format and always include links to data sources, like this example from CT Open Data. Also link to your shared Google Sheets when appropriate.
Give credit to people, organizations, resources, and tools that helped you to create this data story. Write in HTML format and include links when appropriate. When you paraphrase or quote from a specific reading, cite it using any standard academic citation style (such as MLA or APA inline citations), and include the full reference in a bibliography section at the end of your data story. For help with creating citations, I highly recommend the Zbib.org tool. Insert any URL, but you may need to click the Edit button to manually add missing details, such as author and date if the tool does not automatically recognize them, as shown in Image 1 and 2 below.
Image 1: After inserting a URL into the ZBib.org tool, you may need to click the Edit button to manually add missing details.
Image 2: Clicking the Edit button in ZBib allows you to enter or correct missing details, such as the full Website Title.
Below are sample sentences with MLA inline citations that would appear in the body of the data story, followed by the full references that would appear in the bibliography at the bottom:
The City of Hartford recently created a housing code that requires the registration of the full names and contact information for all owners of apartment buildings -- including the officers of Limited Liability Corporations (LLCs) -- in order to "close municipal loopholes that allow anonymous slumlords to operate unchecked" (Lurye).
In most towns, the percentage of high-needs students enrolled in traditional public schools surpasses those enrolled in magnet, charter, and technical schools in the most recent academic year (“Resident Town Export”).
...later, insert a bibliography at the end of your data story:
Lurye, Rebecca. “New Housing Code in Hartford Would Keep Slumlords from Hiding Behind LLCs.” Hartford Courant, May 31, 2019. https://www.courant.com/community/hartford/hc-news-hartford-housing-code-20190531-hcke2jo2x5fpdgz75xf4hlv2ki-story.html.
“Resident Town Export.” CT.Gov EdSight, https://public-edsight.ct.gov/Overview/Resident-Town-Dashboard/Resident-Town-Export. Accessed 29 Nov. 2022.
Optional Hint: To display a clickable web link in the bibliography, look at the HTML code in GitHub for the examples above. See how the URL appears twice: once in the "href" and again in the display text. This is not required for your data story, but it looks good and helps readers to click and view your sources.
All of your data visualizations should be interactive. But if you need to insert a static image, you can upload a JPG or PNG to the GitHub repo, and insert it using the HTML image tag ("img") that points to a source image ("src") stored in your repo, as shown below:
Figure 2: Describe your image in a caption, and always credit the source if someone else created it.
Use subheader tags (such as "h4") to break up long sections of text without creating a new section.
Compose and edit your data story in Google Docs, where co-authors can work simultaneously. When you're ready to migrate to GitHub, create ONE data story template in ONE author's GitHub account, because only ONE person can edit at a time. But the GitHub account owner can go to Settings > Collaborators > Add People to invite a co-author by using their GitHub username, as shown below. But be careful not to overwrite each other's edits!
This template uses Bootstrap background colors. For example, search this "index.html" file for "bg-primary", which sets the navigation bar (line 28), header (line 56), and footer (around line 245) to blue. Changing it to "bg-secondary" switches those colors to gray. Learn about other color options at the link above.
Instead of slowly making edits on GitHub and waiting for them to appear online, you can quickly make multiple edits in your local computer and view them instantly in your browser. Here's a list of steps:
If you need to create a table, first try the Datawrapper Tables tool -- see HODV Chapter 8 -- and embed the results like this:
Table 1: Add your standalone caption here.
A second option is to use the Tables Generator HTML tool. Go to File > Import or manually enter your table data, then Generate the HTML code, and paste it here, similar to this sample:
Header A | Header B | Header C |
---|---|---|
123 | 456 | 789 |
987 | 654 | 321 |
Table 2: Add your caption here.
