Dayton Data Visualization Meetup Website

This is the repository for the Dayton Data Visualization meetup website at We would love for you to join us! Become a member of our group at the website and come to our next event.


We need help with this site. See the current open issues list at It takes a lot to build and run a site like this, but hopefully by enlisting the community, we can make a valuable resource for the Dayton (and beyond) Data Visualization community. We need help with HTML & CSS development, site layout and design, content writing and editing, and tutorial creation.

For some issues, such as editing or writing content, you can submit pull requests directly through the GitHub interface. For edits, navigate to the file you want to change through the website and click the pencil button in the toolbar. For new files, navigate to the folder where you want the file to go, and click the "New File" button in the toolbar. These edits will then go to the site organizers, who will review your changes and either accept them into the project or get back to you with comments.

For other issues, you'll have to get the code running locally. This site is built using node.js and jekyll , which means you'll have to have these tools installed (along with their dependencies) first.


Go to and follow their instructions to get node running on your machine. This site was built with nodejs version 4.1.1, so you may need to upgrade your installation or use a version manager such as n You can check which version of node.js you are running by opening a terminal or console window and typing node --version


Jekyll is a static site generator that helps us keep our content and HTML organized into components that can be compiled into a site we can publish. Jekyll is written in ruby, so the first step is to go to and follow the instructions there for your system. The version of ruby on my machine is 2.2.1. You can check which version of ruby you are running by opening a terminal or console window and typing ruby --version

Once ruby is installed, you can install jekyll by executing the following command gem install jekyll This will install the latest stable version of jekyll onto your machine. I am running version 3.0.1. You can check which version of jekyll you are running by opening a terminal or console window and typing jekyll --version


Though this site is using jekyll to merge our resources into a static site, we will be using npm (a node.js component) to run everything. Open a terminal or console window and navigate to the directory where you checked out this repository to. The first step is to install the development libraries used by node. Execute npm install to download and install the dependencies listed in the package.json file. This should take a minute and will download and install a bunch of libraries into a folder named node_modules. If this command gets interrupted or fails, delete the node_modules directory and try again.

Once the npm install command is complete, execute npm start. This command starts a browser sync session on port 9000 and will watch the src directory for changes. Once you change a file, it will use jekyll to rebuild the site and reload your browser for you. You should now be able to see the site by opening a browser and navigating to http://localhost:9000.

Pull Requests

Once you fix an issue or have a change to make, you'll need to submit a pull request to the organizers for review. You can do this by forking the repository into your own account, making your changes, and then by clicking the "New Pull Request" button on GitHub. If this is done correctly, you should see it show up in our list of open pull requests at
