In the abandoned one, we chose popularities of the movie as x_axis and ratings as the radius of the circle, assuming that since ratings are always between 0 and 10, the size of circles would be stable. However, in the dataset, the movies’ ratings do not vary obviously, and most movies’ ratings are from 5 to 7. Thus it would result in all circles showing in the same size. This display would make it harder to distinguish the differences between movies in ratings, and so we finally choose ratings as x_axis and popularities as radius to solve the problem. \\n\nAlso, initially we wanted each data point to be represented by a star instead of a circle since this ratings are normally represented by stars and this would add to the aesthetic of the visualization. \\n\n $\"1\"$ `","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":397,"value":"md `## Work Split\\n\nAfter deciding what we wanted our final visualization to look like, we came up with different tasks needed to complete it.

After we read the change log of D3 we found that the version of methods was inconsistent. Then we modified the syntax and it worked. \\n\nThe next challenge was how to change the attribute ‘year’ using a slider. We added a HTML input element and used JavaScript method to read the value. And when updating the dots corresponding to year, we encountered the problem that the old version data won't disappear, and the new dots would be added to the last version of visualization result. So we checked the tutorial of D3.js and figured out the usage of enter() and exit().

This made it hard for them to make comparisons among the categories. The users did not utilize the legend as it was intended. They did not realize that the text could be clicked on in order to show data points corresponding to the clicked category. Once they were told the genres were clickable, they felt that this feature resolved the issue of “too many overlaps” and made it easier for them to compare movies within each genre. `","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":385,"value":"md `## Possible Improvements in the Future \\n\nIf we had another week, we would want to create checkboxes instead of simply clicking on the genre legend to display the selected genre. Also, we could use checkboxes to enable selecting multiple genres. \\n\nOn the other hand, since we are displaying four dimensions (budget, rating, popularity, genre) in the visualization, some users might think there are too many dimensions so that it is hard to understand the graph. In our implementation, the genre attribute can be reduced by selecting a specific genre, and we can further reduce dimensionality by adding another checkbox to eliminate the popularity attribute if we could have more time. `","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":401,"value":"md `## Resources \\n\nBubble plot: \\n\nhttps://www.d3-graph-gallery.com/graph/bubble_color.html \\n\nTooltip: \\n\nhttps://www.d3-graph-gallery.com/graph/interactivity_tooltip.html?fbclid=IwAR044wM5KnJx60_XO8sS8MErtrfM5EcTX0_390SliTviqOOxFeiFabPSvhQ#template \\n\nSlider: \\n\nhttps://www.d3-graph-gallery.com/graph/interactivity_button.html?fbclid=IwAR3ktV3OE3zU6ltVl3JjCakYtpzqaprbE6rdzTB9C_NgYM-qXqzB3ab0jYg#text \\n\nLegend: \\n\nhttps://stackoverflow.com/questions/38954316/adding-legends-to-d3-js-line-charts\n`","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":3,"value":"$3e","pinned":true,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"}],"files":"$W3f","stdlib":"1"}} 35:null 2c:[["$","title","0",{"children":"A4 Final Version | Claire Xueqi Ren | Observable"}],["$","meta","1",{"property":"og:title","content":"A4 Final Version"}],["$","meta","2",{"property":"og:description","content":"An Observable notebook by Claire Xueqi Ren"}],["$","meta","3",{"property":"og:url","content":"https://observablehq.com/@clairexueqi/a4-final-version/2"}],["$","meta","4",{"property":"og:site_name","content":"Observable"}],["$","meta","5",{"property":"og:image","content":"https://images.observableusercontent.com/thumbnail/2c8d6d74d11472e92d0eac357d799a8612bd2cdcf9f11e19200caeb20a58349d.jpg"}],["$","meta","6",{"property":"og:image:width","content":"640"}],["$","meta","7",{"property":"og:image:height","content":"400"}],["$","meta","8",{"property":"og:type","content":"article"}],["$","meta","9",{"name":"twitter:card","content":"summary_large_image"}],["$","meta","10",{"name":"twitter:title","content":"A4 Final Version"}],["$","meta","11",{"name":"twitter:description","content":"An Observable notebook by Claire Xueqi Ren"}],["$","meta","12",{"name":"twitter:image","content":"https://images.observableusercontent.com/thumbnail/2c8d6d74d11472e92d0eac357d799a8612bd2cdcf9f11e19200caeb20a58349d.jpg"}],["$","meta","13",{"name":"twitter:image:width","content":"640"}],["$","meta","14",{"name":"twitter:image:height","content":"400"}],["$","link","15",{"rel":"icon","href":"/favicon.ico?favicon.2hqc0rwsy9zm6.ico","sizes":"96x96","type":"image/x-icon"}],["$","link","16",{"rel":"icon","href":"/icon.png?icon.1mhghqfpotdlb.png","sizes":"512x512","type":"image/png"}],["$","$L40","17",{}]] 3d:null
