DATA SOURCE AND DESCRIPTION
DATA CONTENT AND STRUCTURE
The data for the line chart was extracted from an API by Crypto gecko which is a site that has all the up to date information on all the popular Cryptocurrencies. The site provides all kinds of information regarding cryptocurrencies including news and also in different currencies. The data is stored in arrays of 2 with date and value for every cryptocurrency. There are other dimensions to it but for this chart it has been filtered to fit that. It shows the cryptocurrency name and its value in us dollars at any given time in the past. This is then used to plot the graph showing how the data has been changing in the past compared to its value now.
For this particular graph the API used focused on bitcoin in the US dollar. The data was made into a historical chart that shows the different changes of value of bitcoin over time. The three main time periods focused on were 24 hours, one week and one month. The daily graph shows changes every hour for the past 24 hours, the weekly graph shows the changes every day for a week and the monthly graph shows the changes every day for the last 30 days. The structure of the chart was defined with HTML and created using Chart.Js then designed with CSS. Chart.Js uses graph templates which makes it easier and faster to implement.
